Summary:

In a series of experiments incorporating 351nm pulselength of 9, 26, 54, and 625ns, it was found that laser damage thresholds increased as (pulselength)/sup x/, and that the exponent averaged 0.36 and ranged, for different samples, from 0.23 to 0.48. Similar results were obtained when only catastrophic damage was considered. Samples included Al/sub 2/O/sub 3//SiO/sub 2/ in both AR and HR multilayers, HR's of Sc/sub 2/O/sub 3//SiO/sub 2/ and HfO/sub 2//SiO/sub 2/, and Al-on-pyrex mirror; 9ns thresholds were between 0.2 to 5.6 J/cm/sup 2/. When these data were compared with a wide range of other results - for wavelengths from 0.25 to 10.6 microns and pulselengths down to 4ps - a remarkably consistent picture emerged. Damage thresholds, on average, increase approximately as the cube-root of pulselength from picoseconds to nearly a microsecond, and do so regardless of wavelength or material under test. 18 refs.
