Are you trying to say that the temperature makes the crystals alignment change?
Please, for the sake of your eyesight, learn more about safety before proceeding.I've learned a lot so far
The problem with that is removing the KTP crystal from the YVO4 which are adhered together on the small crystal heat sink. It is theoretically possible, but not likely. You could try, but don't be disappointed if it fails.The better bet is to keep the 1064. 808 is just a diode.
Where did you get that from? I have never said the viewing either the beam or the dot on a diffuse surface without goggles would harm you. I only said the the light that you can see is far less powerful than the laser actually is. To me the dot is a faint dark red and the beam is not visible at all. Hence the IR camera. But, absent an IR camera you can see the dot enough to collimate the beam.I have 2 sets of safety goggles that block 808nm. Are you telling me viewing the beam (not the dot) without goggles is going to damage my eyes? Because I kind of doubt that.
I don't see a faint red glow I see a vibrant yet deep red line, the beam itself.
So anyway what's a good solvent for that black glue?
Edit: I was dead wrong the red line I saw was a reflection not the beam itself. My eyes are ok though. Also brake clean makes short work of the black glue.
Edit again: was definitely mode hopping from improperly aligned Crystal's. Now I just need to find that lens that went flying
