LD is Fine. PS is screwed
Recent messings around have concluded that the laser diode is perfectly fine. The wiring of this 808nm diode is different from the 445nm. Instead of being unused, the case pin is actually the anode(+) and pin #2 is the cathode(-).
Furthermore, the laser diode driver that I bought is crap. It’s basically just a resistor. It puts out about 4mA at 2vdc when the bench is first turned on and gradually increases thereafter. If you’ll recall, I need about 2vdc at a constant 300mA. So that thing is junk.
