摘要
以(CH3)2Si(OC2H5)2为前驱体,采用溶胶凝胶与有机合成相结合的方法,制得稳定性良好的涂膜液。采用旋转涂膜法在掺钕磷酸盐激光玻璃棒端面涂制防潮膜,膜层固化后透过率达96.5%,获得的膜层表面粗糙度优良,均方根表面粗糙度(RMS)为1.659 nm,平均粗糙度(RA)平均为1.321 nm[在激光波长1053 nm,脉冲宽度1 ns条件下膜层的激光破坏阈值可达10~14 J/cm2。经过“神光Ⅱ”高功率激光器物理实验运行,膜层使用期为五年,并且已经在我国“神光Ⅲ”原型装置上试用。
Abstract
(CH3)2Si(OC2H5)2 as precursor, a sol of good stability is prepared by sol-gel method and organic synthesization. After the sol is coated it on phosphate laser glass by rotating way, moistureproof film is worked out, having a transmittance of 96.5% after heated. The film has a good morphology, roughness of mean square (RMS) of 1.659 nm and roughness of average (RA) of 1.321 nm. The damaged threshold of the moistureproof film is high to 10~14 J/cm2, tested by a laser of wavelength of 1053 nm and pulse width of 1 ns. In the period of 5 years on “Shenguang Ⅱ” high power laser equipment, it behaves good moistureproof performance , and tryouts on “Shenguang Ⅲ” model.
