Hi! Today I disassembled a Samsung SH-S182D DVD Writer to use the LD.

I extracted the LD sucessfully, is a frame type laser diode, to test which is the red one, I used a driver set to 100mA, what is a secure current.

Here some photos of the LD:




But if I remember, this LD works with less current than the closed/open can LD, so, when I put 100mA on it, the output was too bright, too bright to only 100mA of current.

Someone knows what maximum current I can put without blowing the LD? :thinking:
