4 PIN laser diode?

[o_DEATH_ANG3L_o]

So I tore apart my DVD burner and got the laser diode out. It has 4 PINS on it. Has anyone seen this before? What pins do I hook up to the power? If anyone can help me please let me know.

? Picture please.

Oh hey man you are from youtube. Great videos BTW. I dont have a camera to take a pic with. :-/ But yeah It looks like a normal laser diode and there are 4 PINS on it.

thanks man. that one vid is not good to follow :, but the amount of views is pretty cool lol.

hmm. I would guess it looks like this? I have never seen one, I Just googled this ! Sorry man I have NO CLUE! :-/

provide the dvd manufacturer and model # to us.

Yeah it's an APEX AD-1110.

It is a player, not a burner. The diode will not do squat...sorry.

Ok so what would it do if I hooked it up to power? And why is there 4 pins?

They aren't very common, but occasionally you find 4 pin diodes. Normally there are 3 pin with a pin shared between the laser diode and photodiode. With a 4 pin diodes they are isolated. Unfortunately I can't tell you what pins do what on that diode, sorry.

If it looks like the picture, you can see that one pin is actually connected to the casing, that is your ground or negative, and you need a multimeter with diode testing mode or ohmeter to test the pins and see which one works...

hey its not odd i found a like 12mm 10-pin laser diode in my old early 90's cd player and i dont know what the hell to do with it

How would you test the diode with a multimeter thats got a diode testing mode in it? And what would it do would it light the diode or give you a reading of what mw or ma it is or what ever? Sorry i am dumb! and inexperienced...

Sometimes, the newer 4 pin diodes will have combined IR and visible diode chips integrated into one package...that is how teh blu-ray diodes are, and the way the market could be heading for cheaper manufacturing costs...can you imagine an all in one diode that has blu-ray, red, Ir, Green, etc ? That would be pretty cool to see the technology progress that far !

G !

That will open the door for the "Handheld laser projector" Full with all the colors and everything needed to make it work... ;D Dreaming is only good 1/5 the time... :

A neat toy to find in the attic.OOO

Diode testing mode or simply ohmmeter (they are usually the same on the multimeter) will only tell you if current goes between the 2 pins you touch
