You might have seen one of my old posts where I modded a laser 303 to do yellow @ 561nm, today, I decided to make one lime green @ 545nm, this might be the first one of these made before as I couldn't really find anyone else making one of these, I used Nd:GdCOB (with the right coatings for 545nm) as the laser/doubling crystal (as it is self doubling). It outputs 10mw of 545nm light and all I had to do was swap out the MCA to this crystal (and a bit of aligning) and it's done I'll post some pictures if I can
