Development of high-power laser coatings
Laser resistance and stress-free mirrors, windows, polarizers, and beam splitters up to 400 mm × 400 mm are required for the construction of the series SG facilities. In order to improve the coating quality, a program has been in place for the last ten years. For the small-aperture pick-off mirror, the laser-induced damage threshold (LIDT) is above 60 J/cm2 (1064 nm, 3 ns), and the reflected wa...
متن کامل2.B Perfluorinated Copolymer Coatings for High-Power Laser Applications
Many common crystals for optical parametric processing, i.e., KDP, CDA, etc., are hygroscopic. Preserving their long-tenn stability and optical quality requires immersion in an index-matching liquid contained in some sort of cell.' Several drawbacks derive from this, not the least of which is cost, when up to 1-m beam and cell diameters must be considered for use in fusion-scale laser systems. ...
متن کاملUltra-sensitive Absorption Diagnostics of Thin Films for High-power Laser Interference Coatings
The goal of this project was to demonstrate a simple method to measure absorption loss in thin dielectrics films, in particular in multilayer coatings for high power lasers in which very low absorption losses are required. The absorption characterization method is a photo-thermal technique based on thermal lensing. The method measures the defocusing of an incident probe beam caused by a thermal...
متن کاملDevelopment and application of new high-power laser beam sources
The actual market volume of high-power lasers for manufacturing is dominated by diffusion cooled CO2 laser systems at the multi-kW range and lamp pumped Nd:YAG laser systems at the kW range. Substituting the lamps by diodes the Nd:YAG laser in rod design entered the market as diode pumped solid state laser of the first generation. With output powers up to 6 kW the diode pumped rod is used in in...
متن کاملEvaporated HfO2/SiO2 Optical Coatings and Modifications for High-Power Laser Applications
Evaporated optical coatings fabricated from hafnium dioxide and silicon dioxide are the standard approach for high-peak-power laser components due to the high laser damage resistance of such coatings and the ability to deposit on largeaperture substrates. The tensile film stresses of such coatings may lead to failure, however, particularly in low-relative-humidity purged or vacuum use environme...
