Hi again,
I did try searching the forums, but my search terms contained too many results.
I see on ebay various laser diodes, often these have 2 pins. Others, such as this one:
https://www.ebay.com/itm/1pc-405nm-5-6mm-5mW-20mW-Violet-Blue-Laser-Diode-TO-18/
have three.
I thought if I got 1 that I could use my tester and deduce what the third pin was for, but after doing some research I find that using a tester could damage the laser diode. What is the third pin for?
I also reached out to several sellers asking them what the voltage was for their diodes, it's been several days and I'm concerned that not even the sellers know what they are selling. Is there a way to tell?
Feel free to point me to the fine manuals.
Thanks
