Default Re: 5mw green laser dismonunted

It might be that the driver is powering the laser diode just fine, but perhaps the optics in the brass housing are not converting the output of the laser diode into green. Can you detect any IR using a cheap webcam or camera phone? Don't point laser at the phone. Shine it at a paper and look at the paper with the digital camera to see if you see IR.

It might also be that the driver is bad or the diode was damaged.

It is hard to say for sure.
