Dvd player 4 pin laser diode pinout.

Stay tuned for the next video and feel free to ask questions i. 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. Laser pointed out the window.

Instead i have a 4 pin diode of unknown wavelength color and power. This is how the bare laser diodes look like 5 6mm. Toshiba hd dvd player model hd a2ku newport laser diode driver notes. One of them has an arrow pointing out but none of the others have labels.

4 pin laser diode. A range of small laser diodes is used in laser pointers and bar code scanners. See figure 7 for the area of the near infrared spectrum. I did so expecting to have just a normal 50 200mw 3 pin red diode.

But the laser diode has 4 pins instead of the usual 3. It can be seen that 5mw laser beam is even weaker than the side beams of dvd rw laser. What pin does what. Comparison with laser diode f laser 5mw with power 5mw from gme.

I salvaged a laser diode from a broken dvd player. These types of laser diodes produce an invisible beam at or around a wavelength of 780nm which is in the near infrared spectrum. However the most common laser diodes can be found in cd rom and cd players. Took an old rewritable dvd drive and extracted the red laser diode to use in a future project.

Beam incident on the wall.
