Default Is this laser diode dead?

The 40A laser diode bar I ordered arrived today, but i was looking at it and it looked like the silicon is chipped, i also tested it with a multimeter and current can flow both ways i thought a laser diode is a laser diode?

I don't have anything to power it up but i wanted to know if it is dead which i highly think it is.

sorry for bad pictures but its hard to focus on something small with a crap camera.

Depends on your definition of "dead", but it likely will not work as you want it to. The only way to know for sure is to test it though

Default Re: Is this laser diode dead?

I thought what the heck and tested it by contenting it strait to a battery, it didn't work but after cleaning off the broken silicon it worked.
Because half of the silicon is missing I'm guessing I can only power it up half of the maximum power.
