The flattening property and the laser damage resistance of the treated substrate have been evaluated. Substrate with scratches in one direction was used for the flattening treatment. As a result, scratches with widths less than 0.5 μm were found to be covered smoothly after the 40 minute-deposition. Experiments to evaluate the laser damage resistance of the treated substrates were performed by the fourth harmonic and the second harmonic of Nd:YAG laser. The results indicated that the some of obtained values were high enough compared to the damage threshold of the dielectric multilayer films asuming to use for the high-reflactance mirrors. In the evaluation of laser damage resistance, it was found that a tendency of peeling of the film was due to differences in the absorption coefficient of the two laser wavelengths.}, pages = {83--86}, title = {真空紫外 CVD を用いた光学素子基板の平坦化処理技術に関する研究}, volume = {44}, year = {2015}, yomi = {カワゾエ, ケイスケ and ヤナイ, ヒデノリ and クワズル, ヤスノリ and Kuwazuru, Yasunori and オノ, ソウイチロウ and ナガカワ, ユウヤ and カメヤマ, アキヒロ and ヨコタニ, アツシ and カワゾエ, ケイスケ and ヤナイ, ヒデノリ and オノ, ソウイチロウ and ナガカワ, ユウヤ} }
