3.0 CALIBRATION & ADJUSTMENT
3.1 OVERVIEW
This section includes a System Checkout Procedure, Energy Monitor Calibration Procedure, a YAG Channel
Adjustment Procedure and an Aiming Beam Adjustment Procedure. The procedures assume the reader has
successfully completed a Coherent service training course on the Versapulse Select series.
The System Check Out, Topic 3.2, is an operational check of the system. It confirms that the system turns on
properly, responds properly to operator inputs, provides the full range of pulse energies and pulse rates, delivers
average power within ±10% of the displayed average power, delivers the multiplexed YAG beam into the center
on an attached fiber, and provides an adjustable aiming beam through the fiber. It also checks system coolant level
and consumables (i.e., air filter, DI filter and particulate filter).
The Energy Monitor Calibration Procedure, Topic 3.3, calibrates the voltage output of the three energy monitor
circuits to the field service engineer's calibrated power meter.
The YAG Channel Adjustment Procedure, Topic 3.4, is done when the System Check Out Procedure indicates
a problem with one or more of the YAG channels. It provides adjustment procedures for the channel cavities and
relay optics.
Aiming Beam Adjustment, Topic 3.5, provides information on adjusting the aiming beam optics to get the aiming
beam out through the fiber. See Section 6 for required tools.
3.1.1 Safety Precautions
Lethal voltages and laser emission are the primary dangers to the servicing engineer. In addition to the general
safety precautions which always apply when working on electronics and lasers, the servicing engineer must be
aware of the following specific precautions:
Only Coherent certified VersaPulse Select Service Engineers should attempt any service on this
system.
Even with the keyswitch and the breaker in the "OFF" position there are potentially lethal voltages
present inside the console. Always disconnect the main electrical service before working on the
console.
