Dvd player 4 pin laser diode pinout.

Hi i got a dvd player at an auction in fully working condition for 10. Comparison with laser diode f laser 5mw with power 5mw from gme. Beam incident on the wall. I did so expecting to have just a normal 50 200mw 3 pin red diode.

Took an old rewritable dvd drive and extracted the red laser diode to use in a future project. So since i already had one i decided to remove the insides and extract the laser diode within. Toshiba hd dvd player model hd a2ku newport laser diode driver notes. Laser pointed out the window.

But the laser diode has 4 pins instead of the usual 3. One of them has an arrow pointing out but none of the others have labels. See figure 7 for the area of the near infrared spectrum. It can be seen that 5mw laser beam is even weaker than the side beams of dvd rw laser.

4 pin laser diode. What pin does what. However the most common laser diodes can be found in cd rom and cd players. These types of laser diodes produce an invisible beam at or around a wavelength of 780nm which is in the near infrared spectrum.

A range of small laser diodes is used in laser pointers and bar code scanners. This is how the bare laser diodes look like 5 6mm. I salvaged a laser diode from a broken dvd player. I used the current 48 ma maximum is 50 ma.

Instead i have a 4 pin diode of unknown wavelength color and power.
