An aging flash lamp can be noticed by observing the output energy on a
test run of several thousand pulses. If there are occasional low energy
pulses (perhaps 10-20% lower), then an old flash lamp is indicated. To
replace a flash lamp, the following procedures apply:
•
Disconnect all power to the laser.
•
Remove the laser head cover.
•
Remove the Marx bank printed circuit board from the laser head.
•
Remove the small RED and BLUE start transformer lead from the
terminal strip (see Fig. 4-1).
•
Remove the RED and BLACK flash lamp leads from the terminal
strip.
•
Remove the two recessed screws which secure the pump chamber to
the terminal block and resonator.
•
Remove the pump chamber end caps which secure the flash lamp
(see Fig. 4-1).
•
Straighten the lamp leads and remove the flash lamp from the pump
chamber. Note the position of the RED and BLACK leads.
•
Install the new flash lamp with the RED and BLACK leads
on the same side as the original lamp. Bend the lamp
leads so that they are perpendicular to the lamp.
•
Reinstall the pump chamber.
• Reattach the RED and BLACK lamp leads and RED and
BLUE transformer leads to the terminal strip.
• Replace the laser head cover.
•
Re-install the laser head on the microscope.
