Hi all.
This seems like a very basic question considering the level of some of the threads I've seen so far, but all other sources I've tried haven't managed to help.
Anyway, my question is: can a beam that's partially reflected back into a 532nm diode cause any damage?
Say, from experimenting with non-AR coated lenses?
Also, does anyone know a good source of cheap beam expanders, lenses, prisms, mirrors etc... ?
Cheers.
