Hi Guys,
Im kind of new to lasers but have a strong electronic background. I have a large RGB show laser and the green laser stopped working. :-(
I got a replacement C-mount 808mW 1064nm. This is mounted on a heat sink behind 2 crystals and lenses to get green. easy! I replaced the diode (!Forgot the heat sink compound!) put the whole thing back together and away she went!
After running for about 15min the green started to flash, dim, flash and bright again.
At this point I remembered the heat sink compound, pulled down the laser again, added the heat sink compound and tried again. This time it was a little dimmer but working. So I pulled the unit down for a 3rd time to look for alignment faults, put it back together and it was dimmer again. After much work and trying this and that the laser now is not working at all.
I can see the diode is emitting a red glow but no green after going through the crystals. my question is:
Did i kill the diode the first time i ran it with no heat sink compound?
Was it the heat sink compound that killed the diode?
Can i use heat sink compound or not, maybe i should use something else?
Is there something else i did wrong?
Maybe my diode is ok just cant get it aligned?
Any information on these diodes would be so good!
Thank you everyone for your help with is!
if it is my own silly fault thats ok, ill just try again
