Hd dvd player which was disassembled.
Dvd player 4 pin laser diode pinout.
Beam incident on the wall.
4 pin laser diode.
These types of laser diodes produce an invisible beam at or around a wavelength of 780nm which is in the near infrared spectrum.
I used the current 48 ma maximum is 50 ma.
Took an old rewritable dvd drive and extracted the red laser diode to use in a future project.
Laser pointed out the window.
One of them has an arrow pointing out but none of the others have labels.
So since i already had one i decided to remove the insides and extract the laser diode within.
Comparison with laser diode f laser 5mw with power 5mw from gme.
However the most common laser diodes can be found in cd rom and cd players.
This is how the bare laser diodes look like 5 6mm.
Instead i have a 4 pin diode of unknown wavelength color and power.
But the laser diode has 4 pins instead of the usual 3.
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.
I salvaged a laser diode from a broken dvd player.
It can be seen that 5mw laser beam is even weaker than the side beams of dvd rw laser.
See figure 7 for the area of the near infrared spectrum.
Determining the laser diode pinout.
Toshiba hd dvd player model hd a2ku newport laser diode driver notes.
A range of small laser diodes is used in laser pointers and bar code scanners.
