Laser Diode Pinout. 4 pins??!! Answered
Hi, I got a DVD Player at an auction, in fully working condition, for $10. So, since I already had one, I decided to remove the insides, and extract the laser diode within. I did so, expecting to have just a normal 50-200mw 3-pin red diode. Instead, I have a 4-pin diode, of unknown wavelength, color, and power. Would anyone happen to have a pinout for it? The pins are arranged as below in the picture.
