power meter so that the beam passes through the center of the lens and hits the
center of the power meter.

Gradually increase the current set point to the operating current specified in
the ATP Test Report Data Summary. Do not touch any part of the laser. Wait
for the laser to stabilize for one hour (usually the laser takes about 20 minutes
to reach 95% of the maximum power). Then check if the power is close to the
result on the test report.
Usually the laser needs optimization for the first installation due to the slight
differences of environments, chiller settings and vibration of the transportation. If
so, please follow the laser performances optimization procedures

Maintenance.
Daily Operation
Output energy and repetition rate of the Patara laser system are adjustable over a
wide range. However, operating protocols must be observed to assure operation
without risking internal damage to optical components.

laser performance.
Turn On Procedure
1.
Switch the chiller to the
ON
position. Verify correct flow rate and temperature
setting to value specified on laser test report. Wait until chiller has achieved
proper temperature, which may take five to ten minutes.
2.
Turn the eDrive power enable key switch to
ON
position.
3.
Press the eDrive
POWER
switch. LCD panel illuminates.
4.
Press
MENU
to verify the current and Q-switch settings.
5.
Press
EMISSION
to fire the laser diode after the TEC temperature is
stabilized within the tolerance range.
CAUTION.
The output beam of this system is a safety hazard. Avoid viewing the beam
directly.
6.
Press
SHUTTER
to begin laser output.
Wait for about 20 minutes to reach 95% of nominal output power.
Manual Interrupt Procedure
1.
Press
SHUTTER
button on the eDrive front panel. The
EMISSION
and
LASER ON
indicators will begin to blink. The laser diode current will default
to standby current level while the shutter is closed.
