Need help identifying laser diode from DVD drive

[drummerdimitri]

So out of boredom, I decided to take apart my no longer used LG GH22NP20 DVD re-writer and to was lucky enough to find an open canned red diode which I then pressed into an Axis module which in turn got inserted into a custom made Aluminium heatsink with a small fan to keep things cool and was able to push it to around 3.2V and 700mA, after which, the output power seemed to decrease.

Problem is, I have no way of identifying this diode and therefore cannot know what is the maximum operating current as I would need the datasheet of the diode in order to do so.

I've posted a picture of it along with the details of the DVD unit in hopes of having a better chance of identifying what this diode could be.

Hi
Scrap it and buy a nice 638 Mitsubishi from DTR in a copper module

To be safe keep it around 350mA. Good catch! Deep reds at powers are sooo niccee

Yeah it could be one of those LOC diodes. Your tests pretty much show what it can do and handle. When a diode starts to drop when more power is added then that means you've reached a bit beyond its potential. Ah brings back memories of harvesting diodes from burners
