摘　　要：半导体激光器输出的光束为椭圆高斯光束,若直接用于全息照相非常不利.采用梯形棱镜对将半导体激光器输出光束进行整形,并且在输出光束束腰位置进行全息照相,拍摄的全息图效果非常逼真.Because the output geous to use semiconductor laser field light beam of semiconductor nation. The holograph beside the beam of the semiconductor laser is elliptical, it is always disadvantain holograph. This paper is focused on the orthopedics of the near laser, which will be used in holograph, by trapezoidal prism combiwaist of Gauss beam is also discussed. The hologram is vivid.
