1. Before increasing the pump voltage to bring the laser output back to spec energy, make
sure that your power decrease is not due to misalignment or optical damage.
2. Verify the energy specs by reviewing the Error! Reference source not found. on page
Error! Bookmark not defined. the front of the manual.
3. Position a power meter to monitor the IR energy. If the system has optional
harmonics, measure the total energy of the combined wavelengths. Due to losses in
the harmonic crystals, expect the measured combined total to be 15-20% below
published spec for IR alone.
4. Increase the pump voltage by 20 V on the PCU by the pressing the SELECT button
until red LED is lit next to VOLT-AGE KV on the front panel of the PCU.
5. Now use the ARROW UP/ARROW DOWN buttons as needed to reach +20 V.
6. Open the intra-cavity shutter. Allow the laser to Q-switch and measure the energy.
7. If still below specs, repeat steps 4 thru 6.
Note : If the total voltage increases exceed the installed voltage by more than
100 V, then the flashlamps should be replaced.
8. Check the free-running buffer. It needs to be at least 100 V. See Eliminating free-
running on page 77 .
9. If the energy is back to its spec level, log the date and action in “ Operator Notes” at
the end of the manual and the procedure is complete.
Cooling group contamination
This section describes the procedure for flushing the cooling group if it becomes
contaminated with organic material (algae).
