Thanks for the input. Im looking into the 638nm diode now.

I have a new GhoseDrive2 driver set for 456mA output. I want to build a burning laser powered by one or two 10440 cells. What is the best diode for this project? Thanks for the help!

I am trying to buy a driver for a 660nm diode. I would like to get it from a source in North America. Id like the laser output to be 300-400mw. Size is not important it will be in a 4x2x1 inch enclosure. I have built the "classic LM317T driver" but Im not sure it works properly and do not want...
