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?
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.
