Abstract

We report bulk damage measurements on single crystal quartz and two types of fused silica under single and multiple pulse laser irradiation at 1.064 um and 0.532 um. Whereas the single pulse damage threshold varies little among the materials or with wavelength, the multiple pulse induced damage behavior depends strongly upon material and wavelength. Laser calorimetry and measurements of light scattered during irradiation give no evidence of change prior to the pulse on which macroscopic damage occurs. However, the distribution of the number of pulses needed to produce macroscopic damage as a function of intensity is indicative of an accumulation process in which some minimum intensity is required to initiate the accumulation of microscopic damage.
