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 lens. My circuit schematic is uploaded, except that the potential is from a power supply and not 9V, and R1 is 6 ohms. I would be grateful is someone can spot what is wrong with my setup, because it seems like this laser should be able to burn something. Thank you.
