I'm not sure what that letter has to do with WL sine it's dated August 2005.
Look closer, it has to do with LaserGlow.
It's just an example of what the FDA will do if they find out you've imported a class IIIb laser. Basically they'll ask you to return it and provide proof that you did so.
I don't trust
ANY of the abroad laser sellers, especially Wicked. It's all marketing BS. They're not legal. If you buy a completed laser, where the only thing you have to do is add batteries, and it's over 5mW, it's illegal.
The FDA didn't come up with the accession number system to regulate kids with laser pointer. It's a way of monitor the distribution of any radiation emitting device ranging from industrial CO2 laser to X-Ray machines.
IMO it is cheaper, more fun, and more rewarding to build your own lasers and buy parts separately. If you buy laser modules or diodes it doesn't matter what class they are. They're not technically functioning, so they shouldn't be any issues with customs. I mean what's the point of even being on this forum if you're only going to buy completed lasers and pop baloons? It just doesn't seem like a hobby to me if you're not willing, at some point, learn enough about their construction to build one, and then eventually to expand on the science and provide intelligent feedback to the forum about your finding. This forum is full of intelligent guys who experiment with all kinds of set ups. They push diodes to the limit, plot curves, review batteries, design drivers, experiment with complex optics, and provide write ups on experiments like spectroscopy, fluorescence, diffraction, and interferometry. I myself measured the wavelenght of light to within 5% using a little math, diffraction, and a ruler. Not only that, there are other guys who organize group buys and provide the DIY laser community with awesome deals on sleds and other such things.
But then you have the "I came here because of the arctic" crowd, who bombard this forum with complaints about Wicked lasers and shipping times. That's why I take breaks form this forum for a while. It was great in the past when powerful pointers weren't so mainstream. Now they're so affordable everyone wants one. I remember, back in the day, paying over 500 bucks for 80mW of green. You were hot shit if you had that kind of power.
Ever since that crap happened back in 2005, I've never bough another expensive completed laser from abroad. I think I bought a 25 dollar 50mW pen from LED shoppe at one point but thats it. I only make lasers now. Or if I do buy them completed, I'll get them from a forum member or a US seller.
Sorry for the rant/needed to vent my 2 cents.
