Correlation of Damage Levels at 1.06μm Varying Modal Content and Irradiance History on Representative Coated Laser Optics


This paper reports on efforts to correlate two commercially oriented laser damage tests. The two test facilities are located at Hughes Aircraft Company and Montana Laser Optics.

A variety of coated laser optics have been tested under different test conditions and the damage levels compared. The test parameters varied were transverse modal content, spot size, sample conditioning history and, to a lesser degree, pulsewidth. The accumulated results were correlated by ascertaining the existence of a high probability functional relationship (linear fit) between pairs of damage levels for the same optics under different test conditions. A strong correlation was found between samples tested with the same irradiance history, regardless of the modal content and pulsewidth. Comparison of the samples of different irradiance conditioning history were found not to correlate in general.
