Replying to myself:
I just searched Amazon. There are plenty of green “diode” lasers, 532nm, ~100mW, for very little money. I don’t believe that for a second — those are surely crappy frequency doubled Nd:YAG lasers, probably unfiltered (that filter wouldn’t be cheap, and it might fail anyway under that ridiculous power level), and they will blind you when some funny reflection of the, I dunno, 500mW of stray IR light hits your eye.
Now that real name brand laser pointers are mostly gone, if you actually want green, get a 515nm laser or something along those lines. Stay away from 532nm!
- entropie 2y agoI have a friend with multiple green and red lasers, some from aliexpress. Years ago when the hype wasnt really there he visited me and wanted to show off. I have 3 dogs and I really like this kind of tech but I forbid it to turn that thing on near me, especially in my flat. Even if they are directed away, the chance of unpredictable reflections is just too high for a bit of fun.
