Pulse duration dependence of 1064-nm laser damage thresholds of porous silica antireflection coatings on fused silica substrates

Conference ·
OSTI ID:5618296

We used 1064-nm pulses with durations of 1, 5, 9 ns to measure laser-damage thresholds of 10 porous silica antireflection coatings deposited from both methanol and ethanol solutions containing silica particles with diameters of 10-20 nm. The median thresholds measured at the three pulse durations, 10.8 J/cm/sup 2/, 26.5 J/cm/sup 2/, and 38 J/cm/sup 2/, scaled as pulse duration to the 0.56 power. 4 refs., 3 figs., 1 tab.
