If anyone still wants a laser i got 1, let me know.


2000 mw = $100

Looks cool :)

Yeah they are aweomse :)

I've had a number of high powered lazy pointers for festivals and such. These fucking things are bad ass... I'll probably end up buying one after the first. 

Wait... these lasers are legal around the world, right?  Seems kind of dangerous, does it hurt if it contacts skin at point blank?

Shine it at the attacker's eyes, seems more useful than a taser, lol.

Extremely tempting...

Op makes this thing sound like a pussy, apparently the range is 50 miles, it can burn through t-shirts, credit cards, Rollerblade wheels, plastic toys and can even light a match when the light is reflected by 2 mirrors. HOLY SHIT

Great for people who truly hate drivers in the oncoming lane who refuse to turn off their high-beams at night even after flashing them. Err - I mean, great for bringing down small planes. Err - I mean, great for lighting your friends on fire.

Errr - I mean, great for pointing at the ground, far away from living creatures, and looking at while stoned.

I know they are illegal here in UK, but in other countries they might be legal. You better check,  but even if they are banned don't get caught using one lol :)
Best excuse if you get caught by cops (i use it to point at stars)  8) 8)


Oh go on :P



HAHA  its fun! I remember shining it at a guy at night, he hid behind the car because he thought it was a sniper scope laser hahaha  ;D ;D ;D ;D ;D

They are legal in the USA, but who really cares :P I hear illegal shit gets shipped in boxes all the time. Fuck their gay laws, lazer pointers are the shit :D

where do you ship from?

 Uk or Singapore

I'll take one, PM me we can work out a price. But why is your trust negative?

My trust is negative, how come -_-? I can't see anything :/

Hey, im new here but im really interested in buying 2 of these lasers. I will send u a pm, thanks

EDIT: DUDE

You should take care of this, looks like @MrWDunne wrote you a negative reputation, on a thread that was NOT even his.

Basically, someone tried to scam you by sending you a fake PM with a payment address. This happens all the time.

@MrWDunne thought YOU were posting a fake image and wrote you a negative rating, which is probably effecting your sales.

@TECHSHARE pointed it out here: https://bitcointalk.org/index.php?topic=620239.msg7698656#msg7698656 but @MrWDunne never removed the negative rating on you.

You should email a mod and get this fixed ASAP, its a negative rating on your account that should not be there.

Good luck.

Hey,
This thing is very dangerous! Pointing it to your eye is may be equivalent to stearing at the sun :D
How much for shipping to Bulgaria? You can use this as a self defensive method :)
BR

OP - I updated my post above, please read it.

How can I contact a mod to get it removed, I hate retards that jump into conclusions too quickly lol

Sold 3 lasers :)

Hehe, making a laser 4000mw is not something that i could do lol

However, if the lasers dont get trough customers i will give you a full refund :)

Sent you  a pm:)

To anyone in this thread considering buying one of these lasers, PLEASE consider buying quality laser safety glasses to protect your eyes against this wavelength (532nm). (Sunglasses and welding goggles DO NOT WORK)

 Reflections from shiny surfaces alone can cause permanent vision damage. To the person earlier who said this is like looking into the sun, it's quite a bit more power than that. If the laser can ignite a match, what do you think it will do to the delicate cells in the retina of your eye?



Rant aside, OP do you guarantee that the laser can sustain an output power of >400mW for at least 30 seconds? If so I'll grab one.

Yes everyone please make sure you are carefull as shining it to the eyes can make someone blind...

As of guarateeing that it can sustain an output power of >400mw for at least 30 seconds i cannot guarantee you that, how can i know though? is there a device which calculates output power? thx.

Yes these are not toys and are capable of causing instantaneous eye damage from just a reflection of this beam off of a white wall or other semi reflective surface. I would suggest treating these lasers as you would a firearm. Make sure your friends don't get their hands on it either. I find people have a hard time understanding how easy it is to permanently blind someone with these and will treat it far too casually.

You'll want to grab one of these at the very least if you're going to be selling lasers - http://www.illumn.com/radiant-electronics-x4-3-7w-laser-power-meter.html

I myself use a Coherent FieldmaxII TO with a PM10 sensor, but that's probably more than you'd be willing to spend.

Out of curiosity, is "work output" by measuring beam significantly different from power draw on most lasers? Would guess OP has decent multimeter which, if polls very frequently, could do same test insofar as it measures draw, but again, Idunno if that's a good-enough estimate.

Probably cheaper for him to just send you every laser he sells for free in exchange for testing. ;D

For laser diode based lasers with known hardware you can calculate the approximate output, but these lasers use two crystals inside to change the wavelength of light to the 532nm green that comes out the front end. http://en.wikipedia.org/wiki/Diode-pumped_solid-state_laser
The crystal conversion efficiency can vary greatly with temperature and even between two identical lasers. That's why having an actual power meter is important. Not to mention the whole thing of Chinese sellers padding specifications to increase sales.

Where are these lasers produced ?
USA or China ? I'm just asking because I have purchased  500/1000/2000mw lasers produced in China that only output like 50mw.... not saying yours are these, just asking though :)

cough cough
I'm in Australia... would you be happy to send one to me if I paid ? I would accept all risk of it being taken off me by customs...
/cough cough


and like the poster said. these aren't a toy/joke. You NEED THE SAFETY GLASSES!!!!!!!

These are cool items indeed and I've seen plenty demos of these types of high-powered lasers. But what is the legality of owning one of these in the US? What is the legal threshold for max power? And would you take responsible if case customs confiscates it?

Only problem I've ever seen with lazer pointers in the USA is point them at cops. Tends to freak them out a little for whatever reason :D

Are you saying that from experience?  ;). This is probably true, because it emulates the person being targeted, ie a gun is pointing at them. Although, the laser would have to be red. Haven't seen a green or blue laser mounted on a gun before.

It rings a bell with me for whatever reason. :)

Also aircraft/helicopters don't like them either (this is against the law.)

I remember hearing a story about Schwagstock (music festival that got shut down and the owners in prison) that some kid fell in the fire.  Well, they called the helicopter for him and everyone thought it was a raid.... needless to say people started hitting the chopper with so much laser power they couldn't even land.  

The festival people had let people know it wasn't the FED's.

I've only ever seen the black light lazer that could burn a little shit. This type of lazer listed here is on a whole different level... this fucker belongs in the gun safe if it can focus that amount of power!

Edit:

Here is a green laser for your gun!

Moderators remove trust in extreme situations.
Actually, I'm not sure if moderators can remove trust or if it is solely upto admins.

No mod will remove the trust , you can put trust on anybody's name for any weird or wrong reason , without getting it removed.
You need to contact the person who put the trust in the first place and ask him to remove it.

it seems like it will be illegal to own on of these... can anyone link to specific us laws showing regulations on lasers.

It is not illegal to own high powered lasers in USA. It is however to import them from other countries if they do not comply to safety regulations for things like key interlocks and aperture shutters. (which this laser does seem to have)

Sorry if this is obvious knowledge but a 400mw laser should have no trouble lighting matches/popping balloons EASILY right? By easily I mean <5 seconds, not holding it at a spot for 30 seconds.

updated pictures of laser, and beam, will take more pictures tonight. (3 sold)

It must be 400 mW  ::)

(400 Mega watts would shoot down planes)

Nice product though, good luck with the sales :)

hehe it sure is awesome, i will upload a picture of it in the dark when its darker:)

Just ordered one, will update with a review when it arrives.

posted a pic of beam at night, not very clear thought :( hope it helps

Would you be willing to offer me a refund percentage based on the average output power for a 30 second run (if below 400mW)?

If the laser is damaged, defective, or has other quality issues where the item cannot be used for its intended purpose, i will issue you a replacement or a full refund.

I haven't tested these lasers and don't know if it will work for 400mw for 30 secs straight up, however i did have few viper lasers before 125mw which go for like 150-200$, but i can say that this is much better.

I want one of these lol "poke" my brother with it aey  ;D

LOL! it's fun, i just enjoy it shining it at random people in the street haha
Let me know if you'd like one ill throw in some discount :)

This is so cool. But in UK probably would be seized.

I live in UK, been caught many times. Just say you use it to point at stars, you will get away with it easily.
To be honest, cops don't pay too much atention to those:)

How long does the battery last and is it rechargeable (come with a charger)?

Yes it comes with charger and rechargable battery, i can't give you exact time but it takes a while for it to die.

Bumpy bump :)

If i shine it on my penis can i have an 80% discount?

What do you think?

Yes

No. Id rather you pay me $1000 for it.

Hehehe xD
On a more honest note,  got any more powerful lasers?

 ;D

Yup, most powerfull 1000 MW. But also got 600,800 aswell as 400

Campsis, I am not trolling or anything, I think you are selling a great product at great price.
But the laser you are selling must be mili watt's (mW), not mega watt's (MW).
Kind regards.

Its (mw) , stronger than lasers that go for 150-200$

Yeah - after I saw this thread I google'ed a little, these lasers are beasts!
I remember I had a 5 mW tube-based laser in 1996 when I was a kid, much fun - it could make a dot in the night 500 m away... lolz.
I modified it, so it could carry a AM signal, technically able to transmit a message, if anybody had a receiver.
Nothing compared to the one you sell in terms of power.
Good luck with the sales.

Nice lasers, good luck! :)

thanks! only few left:)

bump bumpy, just received more lasers :)

I'm not asking you where you get them, but is there like a brand or something behind these lasers? Or just sorta generic 400mW?

Yes there is a brand, i can't tell what it is because you will find their company.
However, these are guaranteed laser power (you can test it) if it's not you can get a refund :)

Hmm interesting, you now added a 5w laser. Can you please show a video demonstration of this 5000mW laser in action burning things up? I'd seriously consider getting this if there is proof of its destructiveness.

Do all these lasers have the same body style?

Nope they are different



I will try and get one for you later, going to make bbq now :)

Demonstration of 5000mw laser burning stuff - http://www.youtube.com/watch?v=-lMqZjomAXM

Dat farsi, you make this video?

No, but thats the 5000mw blue one, same power output.

Nah mang, it has to be a video of the actual 5000mW laser you're selling in here. I'm not interested in that blue one from youtube, nor anyone else's.

just updated the prices, unfortunately i no longer have 400mw lasers.

Could you post pictures of the different styles? I'm still interested but I do want one with a beam shutter

This is the body of the laser of 1000/5000mw - https://i.imgur.com/gf6mcTX.jpg   (Please also keep in mind that you can test the output power, and if the laser is not what i have described you will be entiteled to a refund)

I don't have any more pictures, all of my lasers are sealed and ready to be sent out so i dont want to unpack them :) If you are not happy, you can ALWAYS request a refund. So yeah, basically thats the picture of 1000/5000mw laser. As for 2000 mw laser, this is what it would look like :

https://i.imgur.com/PeQJUJl.jpg

Whoa you got some competition here: https://bitcointalk.org/index.php?topic=687839.0

What are the practical difference between green or blue laser, and why should someone choose one over the other?

50,000 MW for 239$ usd, do you really think you will receive the product described? Genuine 50,000mw lasers go for 3000+$,  Even if its 5000mw, i really doubt it will pack that power.

My lasers are genuine, can be tested, and refund issued upon unsatisfaction.

Difference between green,blue,red lasers arent really that much except the colour. However green lasers tend to be more bright..

So which colors correspond to the watt output?  I may be interested in the 2000 mw one, but want to know colors.  Also, do they all have rechargeable batteries and do they come with the charger that can be used in the US?

All colours correspond to watt output, the green ones are usually the brightest ones. However, blue and red are really nice aswell. They come with rechargable batteries and the charger that can be used in us.

Shipping is FREE

Oh so I can get any color in any watt? How long does a battery usually last before needing to be recharged?

If you are interested, I would like to be an escrow for your deal(s).

I will do it for free in return for some positive trust!

I know I am not one of the supreme 'Hero Members' but everybody has to start somewhere.
Thanks!
The only negative feedback I have is from a newbie who tried to scam me then made accounts and gave me negative trust when I reported him.

I will happily provide references of my trustworthiness.

Yeah I just noticed it was listed for 50k mW instead of 5k.

Well I'm genuinely interested in the 5k one, but with that kind of money on a laser, I'd want some reassurance that it's actually close to 5k mW, but I have no real tools to test this. Video would probably come closest to proof, and it has to be your OWN video, not someone elses' for some other laser. If you've never opened the package, how do you know these are legit 5k mW without ever testing them?




No offense but your current track record is appalling to be acting as escrow. Why would anyone want to increase risk going through you? Go advertise elsewhere.

Yes, i would however highly recommend the green one :) About the battery im not really sure, it lasts quite a while i have been shining myne for 3 days and its still going good.

The laser is 5000mw no less, you can do the watt test it certain tools you can buy on ebay or other stores, i haven't got 1 unfortunatelly. But one thing i can guaratee you thought if it doesn't "Cut tape, Burn plastic, Light match, etc etc" or you are not satisfied with it i can easily process you a refund and will pay for a return postage. If you want, i can show you the 400mw laser on skype if you'd like to see it, then you will know what 5000mw could do.

As of the guy who wants to escrow, no thanks lol

What is my 'track record'?
The only negative feedback I have is from two negative trust newbies!

Well to start, you have only been around for 6 months, usually escrow agents have been around a lot longer. Do what I did and sell your own stuff or buy stuff and slowly get rep, now people will send me thousands of dollars worth of goods and I can pay when I receive it. You mist slowly build trust and not dive right in.

Let me check on some funds and ill let you know. Are you open to shipping first and ill pay as soon as it arrives and is tested?

Ok, thanks!

I can ship first for you to test it yes, but as i said you will not be disapointed.
Let me know :)

Great, finishing up some research on the matter and ill let you know.  Basically I am going to Hawaii in December and I want to have this along.  So far I have determined it is legal in the US to own and to use in Hawaii.  Just trying to find if I can bring it on a plane.  Whenever I find someone asking this question all the replies are peoples ill informed opinion which isn't very helpful.  If anyone has any experience in this please let me know.

I think this is a terrible idea. It'll show up on the security detector, and they might confiscate it. Just because it's legal on the ground doesn't mean it's legal on the plane. On a plane it can be seen as a weapon, but I'll await for your research and you can act as the the guinea pig to test it out before I purchase.

You can cary it on the plane for sure, i've carried pepper sprays trought security before. Never i got caught with lasers and i traveled many times, if they question it say it you use it to point at stars. It not that strict as you may think :)

Besides that: I have updated my listing, removed the lasers that have been untested and only listed the lasers that have been fully tested.

HOWEVER - i do think 5,000mw laser for $239 that the other guy is listing, i wouldnt go with that. No way :) I'd rather spend less money for quality item than more money for something i don't know what it will produce.

Anyway, see my listing and if you are interested let me know.

Well I think it should go without saying that they should not be brought on as a carry on, as that can seem weapon like (although many people are saying it isn't a problem as a carry on either).  The TSA do not prohibit them from being brought on planes, but a manager at your airport could still confiscate it.  The main point I am seeing is that you should put it in check in luggage and separate all the parts and take the batteries on carryon (in a computer case or purse).  This way they cannot test it if they open your suitcase.  These seem to be bigger than the "pen" sized pointers, but that shouldn't matter.  If they ask about it, simply say, my family or job likes/requires me to look and point out stars, and this is my main tool to do it.  Worst case scenario, they make you leave it behind in your car or they give it back when you return.  No harm done as they are not illegal.

Now to decide if I want the 2 w or 5 w laser?

Look at his update. Those are the two that he took off from available :(.  Campsis, any chance to test these two? Do you even have them on hand or is it being drop shipped from a supplier? The 2w or 5w are the only ones I'd want, preferably the 5k mW one.

Bump bump

The 2-5k ones are not supplied for me, i have added a 2k one. If interested let me know

Why would you need 2000MW laser anyways? That is just not usable, guess wasting 270$ on it is just throwing money through the window.

What do you mean it's not usable....? dont post nonsense on my thread

next 2000mw sale gets 20% off.

He talked me into buying the 800mw one last night after I enquired about the 1000mw and higher ones.  He told me he would no longer sell over 1000mw and that his prices were wrong for the 800 and 1000 one.  The 800 price jumped up to 160 ish and the 1000mw one jumped up to about 250 dollars.  I said ok I would take the 800mw one and sent half the payment for it and I am still waiting for his confirmation that he received it.  Now when I woke up, he has dropped prices on the 800 and 1000mw lasers back down and has added the 2000mw one back up.  I would much prefer the 2000mw one over the 800mw one and have sent a message asking to get changed over.  Still have not received confirmation that the first payment was received.  Will update once I hear back from him.

Payment received will send you tracking no tomorrow :) I do try to compete with other sellers hence why price changes.

and you don't have time to respond to him untill he posts in topic to tell others his story? Typical scammer attempt

You idiot, i did send him a message after he sent me the funds and he didnt respond to it or posted on my thead saying be bought one. and came today and wrote an essay. :

https://i.imgur.com/ThLkeob.jpg

After that message i went to bed because it was late. Scam attempt hahah i sold many lasers with no probs, stop talking crap. Thx

Couple of tips, take them as you will.  Do not call people on your thread "idiots".  Regardless of what they say or do, it only belittles yourself and makes you seem really immature and will hurt your sales.  Keeping a level head is vital in making sales.  Flying off the handle will only hurt your business.
It was on you to let me know when funds were received, regardless of messages in between then.  This is bitcoinland, where both parties need to be completely informed about what is going on because there is so much uncertainty around everything.  I would hardly call that an essay btw.  I have called out a lot worse for less.  I do not think you are, nor have I called you a scammer in any of my messages/posts, I was simply stating I was unhappy with my current service and giving the exact details of how things have transpired to this point.  I do not think it is at all a question that I wanted the 2w laser over the .8w laser, and can post our messages from last night where you told me they were unavailable and that the 1w ones jumped over a hundred dollars in price, once I said I would rather have that one over the 800mw one.  I will be testing this one to see if it performs as stated (ie I was promised it would pop balloons and light paper on fire), and if not I will be requesting a refund and going after the higher powered one as that is what I wanted.

Apparently my order has been processed and I will have my 800mw laser's tracking number on Monday.  This is more what I settled with than what I wanted, but alas, it is what it is.  I will keep you all updated on my buyer's progress from here on out.

Is that sarcasm?

It appears so.
This seller 'Campsis' seems to have no respect or professionalism towards potential and ongoing customers, especially those with large amounts of trust and forum experience like yourself, a hero member.

It's disgraceful that he puts on a big show and display in the original post, but then his attitude and service drop after you part with your money.

I think I want a refund. Should I give you an address to send the btc back to?

Laser scheduled to be dispatched tomorrow, unless you wait till you receive it and send it back to me i can't, it's the policy.

Just to be clear, the laser has not been shipped, you will not upgrade me to the 2000mw laser, and you will not give me a refund until it has been shipped?

You are not buying laser directly from me, the laser will be shipped to you first thing in the morning. I won't upgrade 2000mw laser unless you willing to pay more. You only will get a refund if you send the laser back, However i will email supplier now and will ask him to cancel the order, i hope i make it in time. Cheers

Of course I would pay more for the 2000mw version. Instead of emailing them to cancel the order, email them to change it to the 2000mw version. I will pay the difference tonight and it can still get shipped first thing in the morning. You still get paid, I get what I want, and everyone is happy.

Ok no problems, sorry for confusion btw. I will try to call them now, maybe their time difference is different. Will update u in 15min

awesome

Whoever bought from me got sent tracking numbers, any problems let me know! thanks

bump bump , 50% off wont be on for long:)

Can I reserve that price for the $85 400mw green laser (so $42.50)? I get paid on the 17th (3 days from now) and I can purchase it then. Thanks. :)

are these shipped from the usa ?
and why would you offer a refund if siezed ? makes no sense.

great price for those in a country where its legal. and for the guy that asked earlier they will burn the skin after a second or two. its a great weapon if someone breaks into your house :p

Sorry to say, they will be pretty useless as self defense. If you are being attacked with fists,stick,knife or gun. You will not have the time nor precision to inflict enough damage before being knocked down. 

If you get it in the eye it will blind them allright for 10secs

Can you recommend some cheap but effective (and maybe somewhat cool looking) glasses I could buy with the 400mw green laser?

i would give you a pair for free:)

Are you serious??? Haha thanks man, I'm so excited to be paid. I can't wait to order off you and have this laser in my hands. :)

Np, glasses are not too expensive but i am willing to provide it :)

Do you have these of other colours by any chance?

Yep, red,blue,green  8) 8)

If visibility is taken out of account, do all three burn the same? I feel like I would want the blue one since the color would be nice. But if the green burns the best, I guess the answer is clear.

All of them are pretty much the same when it comes to burning stuff, however green laser beam is much brighter than any other laser:)

Would there be a discount if I bought 2? :D

Which ones and what colour were you thinking of ?

I'd possibly like 2 400 ones, one green, one blue.

What kind of eye protection are you selling alongside with these lasers?

cheap glassess really :)

^^ These two are saying wise words.

Unless you have good reason to want to own a class 4 laser and proper PPE/installations, buying one "just for fun" means you are a complete and utter fucktard.

https://i.imgur.com/SaKrduw.gif


Jesus. Fucking. Christ.

This is a genuine question, please don't take this as sarcasm or something. But I have no "good reason" for buying this. I just want to have a very powerful laser I can use. Can you tell me "good reasons" for owning a laser like this? I'm curious because although I will be really careful and wear glasses, but in the end, I will be buying it "just for fun" and I don't see anything wrong with that.

Sure, see this:


Shine the laser on a white wall, damage someone else's eyes, what other reason do you need? Just for fun. It is not like there a reason for these things to be banned, they are just silly little toys (that can cause blindness) that shine in real pretty colors. So pretty. I'm pretty sure spending 200+ dollars to burn some masking tape and matches with the laser is going to be worth the risk. Specially with the super-high quality googles that surely will come with the laser.

I asked a genuine question. You replied with sarcasm. I'm asking for USE CASES. Tell me uses of this. He stated that unless you are buying for "good reasons" you shouldn't buy this. What are the "good reasons" ? Tell me some.

No, that's not sarcasm, that's outright mockery, there is a difference.

You asked for use cases to someone who posted about what a colossally stupid idea is to buy those lasers just for fun.

Do you have the proper PPE (personal protective equipment) and the installations to handle a class 4 laser? no? Then you should not get close to them.

Here is a complete list of GOOD USE CASES for those lasers if you don't have the proper equipment and training:

1) There are none.
2) Still none.

Now, if you do have the proper equipment then you can do all kinds of cool shit, like running some laser interferometer experiments for your Physics thesis. Oh wait, that's some really specialized shit. You meant "good reasons", as in silly wastes of time with dangerous equipment. In that case you can:

1) Blind all sorts of animals by mistake
2) Burn all kinds of shit (this is also easily done with matches, they are cheaper)
3) Burn some different shit.

In other words There are no good use cases for those lasers outside some very technical and specialized stuff.

In yet more words, if you're dumb enough to ask for GOOD USE CASES for those lasers to a person who is telling you not to buy them, then you should not get close to those lasers. By the way, just in case you didn't notice, you were dumb enough to do that.

Please don't get close to those lasers (and please don't mistake this with sarcasm, it is supposed to be insulting, you dumb fuck).

The amount of nasty remarks and insults you give to a person who is just curious and wants to learn about lasers is just disgusting. I didn't attack you at all. I didn't say anything nasty to you. I simply asked. Yet you literally called me a "dumb fuck". Thanks for your answer.

http://en.wikipedia.org/wiki/List_of_laser_applications

In that list, there are plenty of things that can be done by your regular, safer, cheaper, available lasers, like making a laser sight.

Of the things that cannot be done by the safer lasers, the only one you can really do without a lot of extra equipment and training is laser engraving, and cutting/burning stuff.  That's it. Those are the use cases you asked about.

Read about them (lasers are indeed cool)  and learn a lot.

There are a bunch of actual legitimate use cases for stupid powerful lasers, aka class 4s.

Laser medicine has a whole bunch of uses:
http://en.wikipedia.org/wiki/Laser_medicine
Don't try these at home.

There are many different applications in manufacturing:
http://en.wikipedia.org/wiki/Laser_beam_machining
http://en.wikipedia.org/wiki/Laser_cutting
There's potential home use here; a relatively benign application is a 2D router laser cutter. Personally I'd start out with something a bit easier like putting a dremel in there, lasers add a legit scary fire hazard to the equation. Containment is also a high priority, because you need to make sure that a stray reflection is in no way putting your eyes (or other people's) at risk.

This brings us to our first PPE side note; ANSI Z136, learn it, love it.
http://en.wikipedia.org/wiki/Laser_safety#Regulations

Quick primer on PPE:
http://en.wikipedia.org/wiki/Laser_safety#Safety_measures
You want wavelenght and power specific eye protection in all cases with class 3B or above laser, and skin protection for class 4.

You want quality, certified PPE. For example, lower class 4 lasers would make me consider at least OD6 protection to cover accidental exposure:
http://www.lasersafety.com/eyewear/polycarbonate/p5e01

Prolonged exposure, higher power and other variables will affect the OD rating required. You are also required to put in similarly rated material in any aperture or viewing window on your laser cutting table.

DO NOT TRUST YOUR SAFETY OR THE SAFETY OF THOSE AROUND YOU BY USING CHEAP, UNCERTIFIED PPE OR OTHER SAFETY EQUIPMENT. If you are unsure of what you need, join a relevant forum and ask for resources and advice.

Beyond that there are plenty of other uses for lasers, but the need for a class 4 laser is debatable at best. A class 3 or even 2B will be plenty for the amateur science dabbler. Same goes for any sane astronomy uses. Definitively stick to class 2B for presentations or messing around with your pets.

Beyond that, just going outside at night with a modest 5mW green laser is tons of fun, so long as you stay courteous to anyone else around you, aka not fucking pointing the beams at people to scare them as certain people *cough*the idiot seller*cough* suggest.

When you've gotten a feel for the various safety issues and what specific project you want to take on, then you build up. Just going 5mW->10mW gives you an appreciable gain in performance, but as you approach 100mW you need to start to seriously think about containment because you have a beam that is an imminent health hazard at short range and a possible distraction tens of miles out.

Going out and just getting a big fuck off class 4 laser without a) a specific application, b) a functional understanding of safety issues and PPE, and c) actual use of proper PPE is beyond insane.

Add to that a whole bunch of issues you have no idea even exists, such as how much IR you laser is spilling. Cheaper models will even have unaligned/ineffective/straight up absent IR filter, which means you could potentially be putting out an order of magnitude more power than you expected, and if your PPE doesn't account for this secondary output wavelength you are in imminent danger.

I could go on and on but tl;dr if you don't know what you're doing, grab a 5mW 532nm green laser to play around with, join a laser enthusiast community and build up from there.

This is fun!

And as a quick addendum, Nd:YAG lasers in 532nm don't have a whole bunch of uses beyond being the most practical wavelength for high visibility applications. At 88% efficiency from the optimal 555nm frequency it has the very cool advantage of allowing for decent usability (ie a laser pointer) in a very modest power output footprint (ideally <1mW to stay around class 2, or <5mW for 2B).

Actual industrial uses require you to kick up the output by several orders of magnitude into the low kW range, aka death star levels of power.

For the laser router I mentioned above, something else entirely is required like a CO2 laser. At 30-40mw it's still a class 4 laser, but it'll allow you to make cuts at a massively more reasonable power level.

What can you use the lasers advertised for sale here for? Pretty much nothing, at least safely. A fixed unit with proper heat management, actual interlocks and much less accidental changes in orientation could be used for a bunch of things. A handheld model is not only less safe, but makes serious compromises in output stability/power management/heat management/bunch of other stuff to be mobile and self-contained.

Fucking seriously, a 2W 532nm as sold here has the power to cause immediate and permanent retinal damage, if not outright blindness, and a ridiculous range up to like a mile and a half. It'll cause a degressive amounts of hopefully temporary blindness or partial vision loss (ie day/week long) up to 5-7 miles.

Beyond that, it's visible up to like 50 miles, so who knows where it'll end up.

Using that kind of output outside of a really, really controlled environment with mass amounts of redundant safety measures is criminally negligent at best. You will cause harm to someone.

Wow OP, pretty unprofessional way to deal with some of your customers. That, and also the fact that these are drop shipped from another source has turned me off from probably getting one. Still following this thread for updates from those that will be receiving these.

The OP and I corrected my issue through PM and I got a tracking number for my 2000mw laser yesterday.  I am not sure if there was just miscommunication on my part or what, but I am happy to say that I am getting what I wanted, and am happy with my purchase.  If this one arrives and everything works to specifications, I may get a lower powered one.

If I might ask, what is your intended use for such a powerful laser?

Burning off his nipples.

This one is just to have.  My family has always had fun with lasers at the beach, and I figured this would be fun for when we go to Hawaii this winter, but I am starting to think this one may be to powerful and I might also order a lower powered one.  But it never hurts, I can use it for self protection in my apartment, since i am not allowed to have a loaded gun per the complex's rules.  This would be a good second.

Be careful, apparently you need special glasses to handle these.

You do not need them if you very careful, they are advised though.  Just don't point them at reflective surfaces and you'll be fine.  In fact, outdoor use in general is probably just safer.

Enjoy your blindness and/or multiple felonious assault charges.

I wish you would do some research before (and not just you, but everyone who is ill informed) spouting nonsense.  I can only be blinded if it hits me in the eye, well, how about I don't shine it in my eye?  And what felonious charges do you speak of?  Cite some precedent where it is illegal to own one of these?  You cannot, so you must be talking about being moronic enough to shine at either an airplane, another person, and animal, a cop, a driver...etc...  How stupid do you believe humanity is?  It really is none of your business my intentions with it.  But please do not harass me if your ill informed.  If someone is stupid enough to shine these at the aforementioned, then they deserve their punishment, and your small post will hardly deter them, but I will not get in any kind of trouble and I hardly need you telling me where I am right or wrong.  Go FUD elsewhere please.

Not to defend him or anything, but I think he means that you might accidentally cause eye damage to another person or animal. Even the scattered light from the laser off of shiny surfaces, like water or buildings, might be enough to cause damage, it doesn't have to be a full beam.

I completely agree, and that is a good warning.  But coming in, and making yourself sound uneducated by throwing things around the way he did, is not the way to go about saying that.  But in all honesty, if someone is buying something like this, and doesn't know how to handle it, is the best way to handle it to say, "have fun blinding yourself and going to jail?"  No that makes you sound like a jackass.

I might have misconstrued the bit about your family and the beach as intent to use it in a public place with other people present. Then again, the bits about using it in a self-defence context and not really needing PPE while using a huge fuck off class 4 laser tell me you don't actually understand safe handling of these things.

But whatever, FUD FUD FUD, it's not like the obviously knowledgeable people in this thread have any kind of actual experience in the safe handling of these things. Nah, the reason why were advising ANSI Z136 compliance is because we're fuddy duddies.

You go right on with your plans to toy around with something that can cause immediate blindness a mile away. All you need to do is be really careful, because a beach doesn't combine huge bodies of reflective liquid, near unlimited horizontal range and the presence of plenty of people.

You can also feel free to ignore the following legal mumbo jumbo, because really, you've firmly established you won't get into any trouble.

Of course using a 2W laser as a pointer is ok, ignore the FDA!
21 CFR 1040.10 (http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?FR=1040.10)
21 CFR 1040.11 (http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?FR=1040.11)

Of course you know all the flight paths of all the planes, ignore the US code!
HR386 (https://www.govtrack.us/congress/bills/112/hr386/text)

Beyond that, ignore the vast amount of state specific industrial regulations, ownership and usage regulations and any number of relevant jurisprudence cases regarding the negligent use of whatever. Again, it's not like your 2W laser has a miles and miles of range at a power level that can cause irreparable bodily harm.

Also anyone in charge of applying OSHA regulation anywhere is actually secret Hitler.

Have fun!

Here a great opportunity to show off all that research you done did about lasers!

How do you plan to address the 1064nm leakage coming from improper or absent filtering after Q-switching the original emission via it's non-linear KTP crystal, without the use of wavelength specific PPE or the use of your blink reflex, in a context of high divergence scattering?

Feel free to put the phrase "localized ocular explosive boiling" somewhere in your reply.

TIA

At work right now, so I really don't have time to look at all of that, but you do seem to have done some research (past copying and pasting I have no idea), but that doesn't matter.  They are not illegal to own in the United States, and proper care will keep one safe.

Besides, we all know they work like this
https://i.imgur.com/ton5Pwz.gif

I'm very understudied in this field. But can I take a stab at this? I'm probably very wrong, but I want to learn. A lot of this is studied from wikipedia and other sources so it might not be accurate. Please don't think I am knowledgeable in this field, I am very new and a complete noob. I'm just putting together some research and things surebet has told me.

A 532nm green laser is not all 532nm wavelength of light. There is 1064nm leakage that accompanies it (known as IR). This is generally undesired because unlike the visible 532nm of green light which causes our blink reflexes to close our eyes in the case of the laser hitting our eyes, 1064nm wavelength IR is not part of visible light, so our eyes's blink reflexes do not work in the same manner. Sometimes, we might not even know our eyes have been hit with high amounts of IR immediately. A sign of our eyes being exposed to 1064nm wavelength radiation is the "pop" or "click" noise that comes from our eyeball. This happens when the retina is heated over 100C, and is known as localized explosive boiling. This is accompanied by the creation of a permanent blind spot. I am not sure how to address this without wavelength specific PPE, but other than being sure the laser you are purchasing has high amounts of 532nm wavelength of light and lower amounts of IR (1064nm), some ways to address this would be to buy proper eye protection that will protect you from both the visible green light (~532nm) and the IR (1064nm). I am still not very knowledgable about the standards of safety glases, but some things to look for are high OD levels (optical density) which is a measure of how much radiation can pass through. I'm assuming the higher this is the better? OD 4+ sounds decent to me. Are there any drawbacks to extremely high OD levels? Also certifications are important. I think the two main are OSHA and ANSI (Z136?).


I'm sure I'm very wrong. Please correct me!

At no point have said that these lasers are illegal.

The FDA said that, bunch of freedom hating commies.



Oops. You also have further regulatory compliance issues such as the obligation to have a keyed interlock on Class 3B an above lasers and a bunch of other things cheap Chinese lasers don't implement.

Can your ridiculous laser make it through customs? It's quite possible, especially if the shipper bullshits his way through form 2877 in the importation process. Of course it's going to have a non-compliant class 3a sticker on it, just in case.

However since May 2014 both the FDA and the CBP are ramping up compliance checks. There are currently 89 companies and 100 originating addresses have been redlisted with regards to laser exportation misconduct.

Right now 21CFR1005.3 only states that your shit is going to get seized so whatever I guess. There is legislation being debated and a serious ramp up in enforcement.

Now please amuse me further by explaining what "proper care" means.

You keep quoting laws and regulations for manufacturers, not for end users.  aka, they do not apply to anyone in this thread (besides possibly OP, but he isn't even manufacturing them).  You will not get your laser taken away if your caught with it, and it does not meet the standards you have quoted.  So I am not sure what you are attacking here?  It seems to be directed at me, but all I have said is that they are not illegal for people to own or use, which you have agreed with, then you have gone on citing regulations that have no relation to the topic (and are a simple google search away).

So not really sure what your getting at here as nothing you have said affects me in any way?

50 mw available? Do you know where they are allowed?

You're funny.

You aren't allowed to import them. I could very possible make it through because of declaration abuse or mislabelling. If found it's seized and destroyed.

Once it's on your desk, in your home, it's fine. Owning it isn't the issue at that point, using it is.

If you use the thing inside your home and take sufficient steps to secure it's use, awesome, no one will know.

Going outside though, there lies the problem.

Using a laser above class 3a as a pointing device goes against 21 CFR 1040.11(b) and 1040.11(c). Since I have no clue where you live, figure out your own state/county/city restrictions that hook into this.

You need to request a variance 21 CFR 1010.4 in theory since you cannot be designated as using a laser pointer, but rather you're operating as a demonstration laser user, aka operating a laser light show.

Since you are no longer acting as an individual with a laser pointer, surprise motherfucker, OSHA comes a-knocking. OSHA technical manual section III Chapter 6 will explain all the various new obligations that you, the end user, have to follow. Table III:6-9 will give you an insight into the wide variety of exciting and expensive engineered controls required for operating a class 4 laser.

You might also want to contact the FAA to verify what's the classification for the sky above where you want to use your laser. Class G means you don't have to worry too much, but as you scale towards class A you might want to ask more questions re: usual flight plans.

You don't seem to understand the power a 2W laser packs. PPE not really necessary if you're "very careful" and basically only a recommendation? There is no MPE with class 4 lasers, but heh, you can just ignore that. Still waiting on you to explain to me how you'll keep yourself and those around you safe, especially with regards to IR bleed through.

Now, with all this, if you don't understand how you can get slapped by anything between public nuisance charge and felonious assault, depending on the recklessness you show, the injuries you inflict and the rest of the context of any incident bound to happen unless you take that 2W laser extremely fucking seriously, I don't know what to tell you.

Look, we understand perfectly how much power a 2W laser packs. It's 2 watts (duh!). The naked lightbulb right on top of me is 30 times as powerful and I don't see the OSHA and FBI busting down my door anytime soon.  Heck, my mining rig consumes around 20 kiloWatts, now that is some power. I had to replace my blown fuses with a couple of screwdrivers but it is fine because I did it very carefully and won't be shining any laser at the breaker box (also, the handle of the screwdrivers is made of wood). Sometimes sparks fly out, I did my research and that means that my rig found a good hash and is celebrating.

https://i.imgur.com/yFGV6QN.gif

For a moment I thought that was real.

Your light bulb is pretty awesome if it has 30 time more light output than a 2W laser  :D

Jeez... I wonder how difficult it'd be to rig up a device which just needs a level above-ground surface to mount the laser onto to be guided on to cut gypsum drywall (can it be burned through like that, even?). It can't be any more difficult than it is for me to trace it and cut with a dremel. I screw it up every freakin' time. Flooring would look like crap if I didn't get to stuff the edges under trim and the toilet. I always measure twice, so I must be fucking up thrice. :D

bump, still got 1 to sell

Not cost efficient:
http://www.ijens.org/vol_11_i_06/118006-3535-ijmme-ijens.pdf

Also the setup you'd need to work on a 4*8 or whatever surface goes beyond the usual hobbyist stuff unfortunately.

If you still have one of those 2000mw green lasers for sale send me a PM i'll buy one this seems like it'll be fun to play around with.

DO NOT BUY ANYTHING FROM HIM, just search through the forums and you will find other reports of him trying to scam. I lost .5 BTC to this guy do not trade with him!!!!

Sorry for those that bought one, but it doesn't seem like you'll be getting anything. Look through this guy's dodgy requests and there are just too many inconsistencies. There's absolutely no proof he even owns or tested any of the lasers here. I was very close to getting one too.

The one dude that ordered the 2W one got a tracking number. I pmed him and he told me it's moving along. So either he's getting a laser or he's getting an empty box. Also, I did see campsis say he was selling his account. I wonder if it has a new owner. He didn't reply to my pm when I asked if we could do escrow for the laser.


EDIT: Two users have "bought" lasers from him:

https://bitcointalk.org/index.php?action=profile;u=354568

https://bitcointalk.org/index.php?action=profile;u=352322

Both have <5 posts. I'm so glad I didn't purchase this dude's laser. All of you people who were warning us about the dangers of these class 4 lasers did more than just keep our eyes safe, you kept our wallets safe lol. Thank you.

Just to end it with the lack of information. Just zero, except the price.

Well, he did have the original thread with pictures/info/things of that sort, he just edited it after the accusations.

I do have a tracking number from China.  EMS said it was shipped to Chicago Sort Facility.  Does anyone know if its possible to track packages after they have left EMS and gotten to the states?

EDIT:  I can't decide if I was scammed or not.  His actions are very sketchy to say the least.  The 2 "customers' who left feedback are definitely suspect, but if he is a scammer, he isn't very good as he is selling under $10 equipment besides the lasers.  It did seem fishy to me though that he messaged me a little while after I got the shipping number and said he had 3 more if I wanted another, I said possibly if he would hold that price for me I would after I got this one, but he never responded, then the next day I asked if he still had it (just fishing for info, wasn't going to give more money until I at least got this one), and still didn't get a reply.  So if he is scamming, he doesn't seem to be very good at it.  IDK, it just baffles me, hopefully a laser will arrive, I am split about 50/50 on whether it will or not.

I really hope you get it man, that's quite a bit of money to just lose like that. :/ Campsis's actions just seemed shady all around, but I agree, he was selling things like pepper spray and such. Seems silly to scam over that.

Yeah hope you get actually get the package. Your transaction will make or break him as being legit or not once you confirm. I was on the verge of getting one, but I didn't want to be the guinea pig.

I mean, even if he gets it we should avoid campsis at all costs. He ignored me when I asked him about escrow.

He is a scammer, my package arrived and it was some rinky dink $5 laser pointer.  Do not do any business with him.  Just glad he didn't get much out of me, hopefully he didn't get anything from anyone else.

Can you post picture of laser to see what reality is to what OP was selling?

I'm sorry you lost your money man. :( Thanks for being the genuine pig though.

OUCH. I kinda expected this to be the case, after see so many red flags. You should have requested for him to ship first, or go through escrow. Scammers will never do escrow.

Hope you saved the packaging. There should be an address from the sender (which is probably him), and if really another company that sent it, at least you can try to call the company to request more info on who requested the package to be sent.

Ha, a fitting end to the thread.


It's been drop shipped from whatever cheap Chinese he ordered it from, the sender's address is of no use.

So the images were fake eh? They looked cool and highly effective. (before the op edit the topic and delete all the images and text). People should escrow with this kind of high risk items.

I don't know how to thank you man, but in the process of warning me of the dangers of a class 4 laser you also just saved me a shit ton of bitcoin. Also, I purchased a 100mW 520nm (not a DPSS laser) in a 501b host off blord on laserpointerforums in addition to eye protection. Excited for that to come in. He accepts bitcoin, so if anyone is interested you should contact him on laserpointerforums.com :) Real nice dude to work with (and he has 1000mW+ blue lasers if anyone absoultely must have one)

He had no images of the actual laser. If you read through the thread, picture and video was requested of the actual laser he is selling, and he couldn't provide it.

I wonder if his other posts were scams too.. seems weird to scam over a $7 product. Maybe he was doing micro-scams? Lol idk, but here: https://bitcointalk.org/index.php?topic=697440.msg7899013#msg7899013

@ DebitMe - you forgot to checkmark the box "This rating is negative", so you actually gave him positive trade feedback. Might want to change that, although I don't think it'll matter too much at this point.

Shameless plug: in case anyone want to buy lasers that actually deliver on their specs, see my sig :)

I wish I had discovered this thread earlier, I could have told you from the beginning that this was an obvious scam. Green lasers at 2000mW are extremely advanced pieces of technology, it is doubtful it would even be possible to make them handheld, let alone in a pointer size running on regular batteries. This thread reads like someone claiming to sell a 1000 horsepower luxury car without any information for $500. It's just not gonna happen. Unfortunately it is common for many laser sellers to lie about powers as many customers couldn't tell the difference between different power levels due to lack of comparisons or power meters.

I have a question about the glasses you sell on your website. Are they just sort of generic ebay/china glasses? It does say OD of 2+ (which is not that high anyway) but how could this be verified?

Yes, they are pretty cheap non-certified glasses. I have measured the OD myself, so I am confident they are safe for hobbyists with the lasers I sell. If you prefer professional glasses, I recommend these: https://sites.google.com/site/dtrlpf/home/laser-safety

Yeah I'm going to get an eagle pair for myself, but I can't be buying 4 pairs of $50 glasses so I need some cheaper pairs for spectators/anyone else. I will probably purchase from you, thanks.

I have no idea why "Wicked Lazers" is allowed to sell hand-held 1W (Class 4) lazers. These things are much brighter than 60W bulbs that radiate in all directions: mainly in the IR spectrum.

There is no way to use them safely. Such powerful lazers are supposed to have an interlock that shuts off the beam if the door of the room (it is permanently installed in) is opened.

I informed the local police about the mere existence of such powerful hand-held lazers. Unfortunately, pilots of the police helicopter can not easily defend themselves against such a lazer because they would have to know ahead of time what colour is being used (If you block red, green, blue and IR for good measure, you have a blind-fold).
