He has taught me the particulars on safety, not the workings of the actual laser. I have some basic knowledge concerning output and light spectrum, but most of it comes from dealing with LEDs for my fish tank. He knows much more about the community and can translate my request into a working laser. Pretty sure if I told you guys I was really interested in a blue light saber that might not be too helpful. The only reason I am on the forum is to clear this up.
