Hi everyone,
Our lasers energy keeps fluctuating (mostly decreasing) after installing second harmonic crystal in front of it. We are using Surelite ND-YAG nanosecond laser. Do you have any idea why it is that?
For reference: 1064 nm power decreases from 1950 mW to 1600 mW in 30 minutes.
Either 532 nm energy increases while 1064 nm wavelength's energy decreasing or vice versa total energy remains constant.
Thanks.
Thanks Dr. Muhammad,
I think its about angle because when I do adjust the knob so I could get maximum 532 nm it is much more stable (not completely stable). Maybe laser energy itself makes change in crystal's angular orientation.
The unit is temperature controlled however we are not sure if it works or not. We just plugged the cable to the appropriate connector.
Thanks again.
