@Anmol444(View Post) The PSCN and NSCN melt fast, that impairs the ability to turn it on/off easily. Photons leak out of the sides. The red colour allows too many photons to rebound and create an unclean cut. I've seen other lasers from you and I'm sure you know that the blue colour is the best for performance.
@CAC-Boomerang(View Post) To fix that problem put a pixel of inst in front of the laser. Make sure that the phot goes through the inst. Then when it bounces back it won't reach the Pscn/Nscn
