摘要 用计算机辅助设计,依靠膜系自身匹配原则,压缩通带波纹,以此提高偏振膜的带宽和稳定性;同时对偏振膜的材料选择、膜系设计以及实际测量进行了研究,并在此基础上设计并制备出以HfO2/SiO2为镀膜材料,使用角度为60°,工作波长为1053nm的多层薄膜偏振片,该偏振片具有良好的光学性能和比较高的抗激光损伤阈值。 Using computer aided designing and self matching of coating system to compress the pass band corrugation, large size film polarizer series with good qualities in a wide spectral range were developed to satisfy requirements for very high power laser. HfO 2 and SiO 2 were used as the material of the film. The work angle of these multilayer film polarizers is 60° and the work wavelength is 1053 nm. Some testing experiments and laser induced damage experiments were done to testify the optical performance and the damage thresholds of the film polarizers.
