-Blue, Violet, almost Ultraviolet really. I am in the process of making a diode driver circuit using a LM317.
+Blue, Violet, almost Ultraviolet really. I made a driver board and just need to finish the heatsink and mount it in a case. I bought a translucent blue project box from Hammond that I'll be mounting the laser in.
