I have a Coherent enterprise 610. I powered it up yesterday, and the unit was only putting out something like 488nm + UV @ about 310mw. ( I could tell becuase I had a flourescent sticky note that glowed white when in the beam path). So I figured it was my mirror aligment, and adjusted, and my power came back to 1.2 watts with all lines. NOW, like an idot, I was using my tune function to peak out all the power (manualy) and.... BLINK... I lost the beam.
I just spent 2 hours, on setup of an alingment jig. I now have my beam back, but once again I only have 488nm +UV. Only at about 54mw. I was @ 485mw @ 9.2 amps. If I fiddle with the mirrors (lightly!) I can see some of my green lines come back. Also If I run full power (24amps) I can see all lines...
Do you think my mirros, are dirty, and need to be removed, and cleaned? or is it just the angle of which I re-alinged my beam on the mirrors?
Any help would be nice!
