Hello guys,
I have had a problem in the past with green laser diodes, they don't work in the cold. I've had a few cheap ones in the past, that once they are exposed to the cold, the beam output drops. I have a 50mW diode on the way. I don't know if the driver is made to be ACC or APC.
In the event that the diode dies in the cold, I had an idea to warm it up. I want to wire a 3 position switch into a custom host. First position is off, second is on, third is warming mode.
I want to take a resistor to limit the current to about half an amp. Then I want to run either magnet wire or hookup wire looped around the diode. When it gets too cold, I switch to warming mode, the wires heat up from the current, and warm the diode.
I'd like some feedback on my idea.
