Tsunami Symptom: PZT oscillates when LOCK is enabled. Possible Causes Inappropriate gain setting on the Model 3930. Bad PZT mirror assembly. Corrective Action Contact your Spectra-Physics Lasers field service representative. Replace the PZT mirror assembly. Symptom: Laser rep. rate is unstable or > 80 MHz. Possible Causes Pump power is too high (ps configuration) Pump power is too high (fs configuration) Corrective Action Check for real satellite pulses by turning the GTI POSITION control on the laser head control panel. If the pulses are real, i.e., they move away from or closer to the main pulse as the POSITION control is adjusted, they are caused by high pump power (cw breakthrough). Turn pump power down until the satellites disappear. Refer to appendix B, "CW Breakthrough." Tsunami power should still meet specification. If not, contact your Spectra-Physics Lasers service representative for help. If the satellite pulses are real, they disappear when you block the pump beam to the Tsunami. If they are phantom, see "Room lights" above. If you have real satellites, they are caused by high pump power (cw breakthrough). Turn pump power down until the satellites disappear. Refer to appendix B, "CW Breakthrough." Tsunami power should still meet specification. If not, contact your Spectra-Physics Lasers service representative for help.
