affect beam quality. This procedure instructs you on how to increase flashlamp pump voltage

to compensate for lamp aging.

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.
