1 前言在激光核聚变中需要大量使用大尺寸、高精度的光学元件。例如 ,直径达 6 0～ 10 0cm的反射镜 ,40～ 80 cm量级的聚焦透镜及激光窗片 ,对应于直径 35 cm光束的激光玻璃等 ,均要求以λ/ 6以下的波前像差制作 ,供装置使用。这些光学元件几乎都采用研磨工艺制作 ,尤其是大尺
1 Introduction In the laser fusion requires large use of large-size, high-precision optical components. For example, a mirror with a diameter of 60 to 100 cm, a focusing lens and a laser window of the order of 40 to 80 cm, laser glass corresponding to a beam of 35 cm in diameter and the like all require wavefront aberration of λ / 6 or less Production, installation for use. Almost all of these optical elements are made using a lapping process, especially large ones
