| 摘 要： | 利用相位匹配条件,坐标转换和菲涅耳公式推导出了可调分束角棱镜的光强分束比的数学表达式,分析了光束的入射角、棱镜的结构角,以及入射波长对光强分束比的影响,给出了使光强分束比为1的条件,并进行了实验测试,测试结果与理论分析相一致,为设计出射光强相等或近似相等的可调分束角棱镜提供了理论依据。

Study about splitting intensity ratio of a prism with variable beam splitting angle |
| |
| Abstract: | The mathematical expression of beam intensity splitting ratio of a pr i sm with variable bean splitting angle is obtained by means of phase matching con dition, coordinate conversion and Snell's law. The relationship between the beam splitting angle and incident angle, structural angle and wavelength of incident light is analyzed separately. The condition that beam intensity splitting ratio get a value of 1 is given, and the result of an experiment conducted according to this is in coincidence with the theoretical one, which provides theoretical b asis for the design of beam intensity splitting prisms with beam intensity split ting ratio of 1. |
