WebAug 11, 1999 · Single- and multiple-shot damage thresholds and plasma-emission thresholds for fused silica and CaF2 are reported for 790 nm photons as a function of laser pulse width (190 fs – 4.5 ps). The results … Expand WebSun Laxi found that RIE technology could significantly improve the laser induced damage threshold (LIDT) of fused silica optics . Under the conditions of 355 nm wavelength and a single longitudinal mode with about 3 ns (full wave at half maximum, FWHM), the 0 probability damage threshold could reach to 7.5 J/cm 2 after the RIE process.

WebLaser damage in fused silica, particularly ultraviolet laser damage, is still a key problem limiting the development of high-power laser systems. In this Letter, a combined process of chemical etching and CO2 laser polishing was applied to ground fused silica. A super-smooth surface with a root-mean-square roughness of 0.25 nm was achieved through … WebDec 22, 1998 · A study was conducted to understand the effects of etch depth on the damage threshold of fused silica substrates. The study used a 355 nm, 7.5 ns, 10 Hz Nd:YAG laser to damage test fused silica optics through various wet etch processing steps. Inspection of the surface quality was performed with Nomarski microscopy and … WebDec 3, 1996 · The silica windows were then illuminated repetitively using a 3-ns, 355 nm and an 8.6-ns, 1064 nm laser. The tests were conducted at near normal incidence with particles on input and output surfaces of the windows. During the first shot, a plasma ignited at the metal particle and damage initiated on the fused silica surface. little girl wedding dress
