Contamination Resistant Sol-Gel Antireflective Coatings
Silica-based sol-gel antireflective (AR) optical coatings are critical components of high peak power laser systems. Water vapor and volatile organic compounds can contaminate these coatings, reducing both their antireflective efficiency and laser-damage resistance. Previous work has shown that alkylation of free hydroxyl groups on the silica sol-gel with organosilicon compounds in solution can ...
متن کاملContaminant Resistant Sol-Gel Coatings
Valerie Rapson Greece Olympia High School Advisor: Kenneth L. Marshall University of Rochester Laboratory for Laser Energetics Summer High School Research Program 2005 1. Abstract Sol-gel coatings are used on the OMEGA laser optics as anti-reflection (AR) coatings to maximize their transmittance. Over time, trace organic compounds in the laser bay contaminate these sol-gel coatings, reducing th...
متن کاملEffect of rheology and processing parameters on the EPD coatings of basic sol-gel particulate sol
Homogeneous thick silica coatings were prepared onto metals substrates by Electrophoretic Deposition (EPD) using particulate sol-gel sols. The synthesis of the sols was performed by mixing tetraethoxysilane and methyltriethoxysilane under basic catalysis. The synthesis, storage and processing conditions were optimised, correlating the rheological properties of the sols with EPD performance and ...
متن کاملAbrasion Resistant Anti-Reflective Sol-Gel Coatings
Many optics in both the OMEGA and OMEGA EP lasers are coated with anti-reflective (AR) silane sol-gel to maximize their transmittance. Although these coatings are highly resistant to both airborne contaminants and laser damage, they are susceptible to mechanical damage by abrasion, and thus require extra care during the handling, installation and alignment of sol-gel optics. Previous “hardened”...
متن کاملSynthesis, characterization, of Fluorohydroxyapatite nanopowders by sol-gel processing
In this work, sol-gel processing was used to synthesize the fluorohydroxyapatite (nano-FHA, Ca10(PO4)6(OH)2−xFx) nanopowders. The advantages of the sol-gel method over other methods are precise control of composition, low processing temperature, and better homogeneity. Calcium nitrate tetrahydrate, phosphorous pentoxide and Tetrabuthylammon...
