Hey guys, sorry if this is in the wrong area but... I started to take apart my old DVD-RW Drive and I am STUCK!

I took some pictures of where I am at, but I don't know which part I need to disassemble for the laser diode, or how to disassemble it. Does my DVD-RW Drive have 2 different lasers in it? Which one is which? What do they BOTH do?


Is this where the laser diode is?

Or is it here?


Any help please?!?!

Thanks,
Josh

i don't see a the diode, only the lenses in the pics. you might also want to consider resizing it

Trace back the copper ribbon cables.  They will be soldered onto the pins in the back of the diodes.  There will be either three pins or four pins (probably).  After you have those found, show us some more pictures.

Peace,

**EDIT** [/highlight] What did this come out of? (model, write speed, etc.)

Alright guys, I found my laser diodes!

Correct me if I am wrong, but the diode with the heat sink is the red laser, and the diode without is the IR?

Picture:

It looks like they may just be "glued" in place.  See if you can carefully twist or "lever"/pry the heat sinks free of the sled.

DO NOT do this by grabbing the pins!!!! Grab the heat sink.

Peace,
dave

I got them out, they were just glued in...



Which one do I want, left or right?

Also, I do have a mini flash light I would like to put it in, but, can I run 3 aaa batteries to this diode safely?

the one on the left looks like an open can red DVD burner diode

Definitely not a good idea. Nothing is going to stop the batteries from putting out WAY to much energy. You should use a driver. You can make one or buy one but without it you are putting your precious diode at risk.

Make: http://www.laserpointerforums.com/forums/YaBB.pl?num=1185701612

Buy at: http://www.laserpointerforums.com/forums/YaBB.pl?num=1206947255 (you need about 6-12 volts)
or http://www.laserpointerforums.com/forums/YaBB.pl?num=1209418066 (you need 2.5-5.5 volts)

an open can red is a very good diode ;) you will need a flex drive or rkcstr driver to regulate the current and a heat sink to keep it from burning up. also a aixiz module to house the laser.
