随着激光应用面的扩展,光学元件的重要性更多地受到关注,其中之一即是反射镜的精度。特别在核聚变及红外波段大功率激光装置中,为尽可能提高反射率而提出了反射镜的精度问题。在日本,受通商产业省的“超高性能激光复合生产系统”计划的委托,东芝机械公司进行了开发研究,最近,曾在1980年9月芝加哥市的国际机床展览会上成为谈论 With the expansion of the laser application area, the importance of optical components has drawn more attention, one of which is the accuracy of the mirrors. Especially in the nuclear fusion and infrared band high-power laser devices, in order to improve the reflectivity as much as possible, the accuracy of the reflector is raised. In Japan, TOSHIBA Machinery Co., Ltd. was commissioned by the Ministry of Trade, Industry andsushino's “Ultra High Performance Laser Compound Production System” program and was recently discussed at the International Machine Tool Fair in Chicago in September 1980
