Contaminant 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...

Abrasion 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”...

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 ...

Current Research Status of Corrosion Resistant Coatings

The recent patents on corrosion resistant coatings were reviewed in this paper. The materials of corrosion resistant components, e.g., metals and alloys, ceramics, polymers as well as composite materials, developed for environmental, economic and other concerns were discussed. In addition, the novel methods for forming the coatings, including the powder floating by vibration and the precursor g...
