Dvd Player 4 Pin Laser Diode Pinout

I salvaged a laser diode from a broken dvd player.
Dvd player 4 pin laser diode pinout. Instead i have a 4 pin diode of unknown wavelength color and power. Comparison with laser diode f laser 5mw with power 5mw from gme. These types of laser diodes produce an invisible beam at or around a wavelength of 780nm which is in the near infrared spectrum. So since i already had one i decided to remove the insides and extract the laser diode within.
Stay tuned for the next video and feel free to ask questions i. I did so expecting to have just a normal 50 200mw 3 pin red diode. However the most common laser diodes can be found in cd rom and cd players. Hi i got a dvd player at an auction in fully working condition for 10.
One of them has an arrow pointing out but none of the others have labels. It can be seen that 5mw laser beam is even weaker than the side beams of dvd rw laser. But the laser diode has 4 pins instead of the usual 3. 4 pin laser diode.
Determining the laser diode pinout. This is how the bare laser diodes look like 5 6mm. I used the current 48 ma maximum is 50 ma. A range of small laser diodes is used in laser pointers and bar code scanners.
