1064—NM Laser Damage Thresholds of Polished Glass Surfaces as a Function of Pulse Duration and Surface Roughness

Source

Laser damage thresholds were measured for four polished glass surfaces, using linearly polarized 1064-nm pulses with durations of 0.17 ns, 1.0 ns, 1.6 ns, and 3.2 ns. Thresholds scaled approximately as the square root of pulse duration, but were insensitive to variations in surface roughness when the roughness was <25 Å rms. Careful cleaning increased the damage threshold at 3.2 ns by removing parti culates.
