摘　　要：根据光在马普-赫斯棱镜两空气隙胶合层中的干涉效应,分析了其对单模高斯光束光强分布的影响.结果表明,对于某一高斯光束入射棱镜时,透射光束光强将随入射角的变化而呈现周期性的振荡;对于正入射的光束,当空气隙的厚度一定时,透射光强随棱镜两空气隙结构角的变化作周期性振荡;当结构角一定时,透射光强随空气隙厚度的变化作周期性变化;且透射高斯光束的形状也随棱镜结构的改变发生变化,表明,可以通过选择合适的棱镜结构以减小棱镜对透射光束的影响,对于成品棱镜,则可通过改变入射角使棱镜的性能达到较佳状态.Based on the interference effects happened at the two air-gap cementing layers of Marple-Hess prism,the transmitting characteristics of single-mode Gaussian beam passing through polarizing prism are analyzed. The results indicate that the transmission light intensity oscillates in period by changing the incident light angle at the interface of the air-gap layer. For the normal incidence light, the transmission light intensity oscillates in period by singly changing the structure angle or by singly changing the thickness of the air-gap layer. The shape of Gaussian beam is also changing with the structure of prism. This shows that we can reduce the effects of Marple-Hess prism on single-mode Gaussian beam by choosing the appropriate structure of the prim. For the finished prism,it can make the prism on the optimal state by changing the incident light angle.
