K9玻璃是一種性能優(yōu)異的光學(xué)材料,作為激光薄膜的基底,其抗激光損傷的特性和能力,直接影響高功率激光薄膜的性能,特別是對(duì)激光增透,偏振膜。本論文采用10ns的1064nm激光,實(shí)驗(yàn)研究了K9玻璃前后的激光損傷特性,用Normaski顯微鏡分析損傷圖貌,結(jié)果顯示玻璃前后表面的激光損傷表現(xiàn)不同,前表面主要表現(xiàn)為燒傷,后表面主要表現(xiàn)為破斑,前后表面的損傷閾值之比約為1.4。后表面的損傷形貌與前表面相比,基本為災(zāi)難性損傷,多次激光脈沖打擊顯示,后表面的激光損傷尺度隨著激光脈沖數(shù)呈指數(shù)增長(zhǎng)。 As the substrate of laser coatings, the laser damage characteristics of K9 glass can directly influence on the performances of laser coatings such as AR and polarizer. In this paper, the damage of glass has been studied by use of a 1064nm longitude mode, 10 ns Nd:YAG laser, the laser damage size and morphology arc observed and analyzed by using a Normaski microscope, the results show that there is obviously different for characterization and threshold of laser damage between front and back surface, the damage threshold of back surface is 1.4 times lower than that of front, and the crack damage is more serious than scald damage on front surface. In addition, the damage size of back surface show exponential growth with laser shot numbers
