Configuring Automatic Mode (INT/INT)
To configure the ICE450 in Automatic mode:
1. Use the
Flashlamp
menu to set
flash sync
to
INT
.
2. Use the
Q-Switch
menu to set
QS sync
to
INT
.
With these settings, when the “Q-Switch Start” and the “Flashlamp Start”
buttons are pressed, the ICE450 automatically generates the flashlamp
discharge pulses and Q-Switch pulses; there is no need for an external
signal generator.
The ICE450 generates flashlamp pulses at the rate specified by the “freq.”
setting from the Flashlamp menu. This setting is adjustable for stable
resonator type laser heads.
Note:
For GRM type Laser Heads, the frequency may only be adjusted to
± 10% of the frequency set at the factory. Refer to the
that was shipped with your system for the frequency value set for
your system.
The ICE450 may be set to generate Q-Switch pulses internally. They occur
after the flashlamp pulse at a time specified by the “FLQS dly” set from the
Q-Switch menu. Adjusting this delay is one method of adjusting the optical
energy of a laser pulse.
To use the Remote Box to initiate laser operation in automatic mode:
1. Press the “Flashlamp ready” button.
2. Press the “Flashlamp start” button.
3. Press the “Q-Switch start” button.
