摘　　要：论述用于把窗口尺寸为０－１２８５ｍ ｍ ×３ ．２３９０ ｍ ｍ 的半导体激光器发出４４°×１３°的发散光束压缩成在±０－００２５ｒａｄ 内出射光的柱面镜系统。该系统的核心是用两组互相垂直、且共轭距相等的双曲柱面镜，把激光器的条形窗口的像变粗变短；然后，再用透镜组把此像“准直”到“无限远”The hyperbolic cylinder lenses used compress beam from semiconductor laser is argued. The system compress diffusing light beam 44°×13° into±0 0025 rad from the semiconductor laser. The side of the laser window is 0 1285mm×3 239mm. The key of the system is that cylindrical lenses by perpendicular double group and equal conjugate are used to image marking shape window to thick and short one. Then lenses are used collimate the image to infinite.
