Resonator Optics Inspection/Replacement Procedure, PDL
1. Unplug the system.
2. Remove the fiber block.
3. Remove and lay the display assembly module down on the main chassis handle.
4. Remove the internal monitor assembly.
5. Inspect the maximum reflector and output coupler carefully for burns or other
degradation. Use a flashlight and compressed air to aid in the inspection. If any damage is
noted, remove the optic with the mount and clean it. First, loosen a compression fitting on
the head for the dye solvent to drain the solvent away—the lines should appear clear
before an optic is replaced.
6. Remove the four, 4-40 screws that hold the optic to the end plate.
7. Clean the optic carefully using methanol and a lens tissue or cotton swab. If the optic
cannot be cleaned, replace it.
8. Install the optic with the mount.
9. Normally, if the damaged optic was aligned, its replacement should have sufficient
alignment to lase. If the alignment process is being done from scratch, tighten the four
screws that attach the holder to the end plate, and then tighten the three screws that align
the optic using the compliance of the O-ring. Fully compress the O-ring, and then back
off one turn for adjustment on each of the three screws.
Pump Chamber Replacement Procedure
CAUTION: Before removing the pump chamber, always remove the lasers AC line cord
from the wall receptacle. Use a digital voltmeter to make certain that there is no voltage
present on the capacitor bank.
1. Access the laser resonators.
2. Remove the rear bridge and disconnect the fan.
3. Remove the fiber block.
4. Drain the water.
5. Disconnect the coolant lines from the pump chamber being serviced. Disconnect the dye
lines for the PDL head. The dye solvent does not have to be drained at this time.
6. Disconnect the lamp leads from the lamp(s) to be replaced by loosening the 2, 4-40
socket heads on each of the flashlamp collars.
7. Disconnect the red wire from the trigger transformer that is attached to the pump
chamber.
8. Remove the rear 10-32 nut that holds the end plate of the resonator to the rubber mount.
9. Remove the four 4-40 socket head screws that secure the pump chamber to the head
mounting plate. Carefully remove the pump chamber from the laser.
