    CNC 445nm 2W laser cutter problems

    My circuit is a constant current regulator. The laser diode I am using is a M140 which does have a very bright beam that is focused to a small point. I've let it sit for a minute or two focused on one spot but burning occurred.

    Hello everyone. I am not as experienced of a laser enthusiast as most of the people on here, but I'm trying to learn. I am a student of physics at Portland State University working on some laser projects but I have minimal experience with building my own circuits. Any help from this community...

    CNC 445nm 2W laser cutter problems

    Hello. I am working on a laser cutter for a class project. I have built a laser driver for my laser diode but it will not burn anything. I am running .27A through the diode with a measured potential of 5V which should output 1.5 watts. The laser diode is placed inside a Aixiz housing with a G2...
