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 Chapter 5:

Daily Operation

Output energy and repetition rate of the Iklwa laser system are adjustable over a wide
range. However, operating protocols must be observed to assure operation without
risking internal damage to optical components. Table 1-1 summarizes laser performance.
CAUTION.
directly.
Turn On Procedure
1. Switch the chiller to the ON position. Verify correct flow rate and temperature
2. Turn the TEC controller and wait for the temperature to stabilize.
3. Verify the current and Q-switch settings.
4. Supply current to the laser diodes.
5. Open the shutter to begin laser output.
Wait for about 20 minutes to reach 95% nominal output power.

and chiller are stabilized, set the current at 10 A and begin current flow to the
diodes. Open the laser shutter. Gradually increase the current until the laser is
firing at very low power. Move the negative lens and power meter so that the
beam is passing through the center of the lens and hitting the center of the
power meter.
the test report. Do not touch any part of the laser and wait for the laser to
stabilize for one hour (usually the laser takes about 20 minutes to reach 95%
of the maximum power). Check if the power is close to the result on the test
report.
The output beam of this system is a safety hazard. Avoid viewing the beam
setting to value specified on laser test report. Wait until chiller has achieved
proper temperature, which may take 5 to 10 minutes.
