So I recently built my own ~1W 445nm laser in an Altoids tin following an instructable. I'm powering an M140 diode (DTR-LPF) using two 14500 3.6V batteries and a 7805 voltage regulator (no extra protection). The circuit works, but I seem to only be getting a dim spot. Anybody have any ideas as to why my system doesn't seem to be outputting anywhere near the ~1W it was intended to?
