Default Diode removal from DVD-rom

Hey everyone,

I recently went out and bought all (or most) of the equipment i needed to build myself a laser. Everything i've setup so far has gone flawlessly but the only place i'm having great amounts of trouble is removing the laser diode from the actual lense holder. The DVDrom i had taken apart was a lightscripe 20x lg burner. I'm even more pissed because it was an open can diode - but i broke it because against all attempts i could not remove the alluminum support surrounding the diode in the burner - it was glued in with some heavy duty material and had no luck trying to melt it with my saudering iron or chipping away at it with a flathead. I'm normally a fan of trying things yourself first, and if unsuccessful ask for help...but i think i went a little overboard and ended up throwing away 50 dollars.

Anyway, the reason of this post was because I curious what methods you all have used to extract the diode from the lense holder. Which were successful and which weren't? why? and perhaps pictures I don't know if something like this already exists, but it could serve as another good reference for what to do and what not to do when attempting to build your laser.

Maybe this thread will help:

But usually I take a wire cutter and cut the heatsink. Then the heatsink will usually separate enough for the diode falls out.

I am thinking about ordering a couple of the DVD burners referenced in this thread. It sounds like they are very easy to harvest diodes from.

I have these heavy duty style crimpers with cutters at the end. they cut through that pot metal like butter and eat that epoxy for dinner.
