PBS uses glue between two prisms. The glue absorbs low wavelength light like blue, so PBS will burn. We use other in place of PBS in our 445nm 2W to 6W lasers. This kind of optics would not go wrong.

Insanity where did you get your PBS from? Was it a broadband or was it strictly for 445nm?
Could you move it over a little bit to a fresh area of the PBS and turn down the power a little bit?

Chris (Badger1666) sorted me out with a BB cube in the end... There is absolutely no space to move the existing cube in the lasers... Very tight for space, 2 diodes, waveplate and cube all crammed in there... I have 3 of these lasers and only had one dodgy cube so far, so I am guessing it was one of a bad production run...Originally Posted by LaserCo
