For AVIA Lasers
Stabilize head baseplate temperature.
Verify that the ambient temperature is not excessive, or abnormally unstable. If the head is water-cooled, verify the water flow and temperature setpoint are correct.
Run the laser at normal operating conditions, and record the head baseplate temperature hourly, over the course of a day, in order to determine the variation in the head baseplate temperature. Consider whether the variation in head baseplate temperature correlates with the variation in beam pointing. If the head baseplate temperature varies markedly throughout the day, water cooling of the baseplate is recommended.
Perform all Temperature optimizations and Therma Track optimizations (for non0Ultra systems) as described in the operator's manual.
If after verifying and/or correcting the checklist items the system is still not operating contact Coherent Technical Support at 1-800-367-7890 or your local service representative for assistance.
