Paper Abstract

Using photo-excited silicone oil developed a new protective hard coating method for high power laser to present the tolerance in water. The silicone oil was spin-coated onto the surface of an optical material and then irradiated with a xenon excimer lamp in the air, which transformed the organic silicone oil into inorganic glass. This technique has enabled an optical thin film capable of transmitting ultraviolet rays of wavelengths under 200 nm and possessing the characteristics of homogeneity, high density, resistance to environmental effects and to water, anti-reflective in water, and Mohs scale value of 5.
