Effect of Rochon prism on single-mode Gaussian beam

In order to study the effect of Rochon prism on single-mode Gaussian beam,the interference in the cementing layer was analyzed in detail.The results reveal that for a given incident single-mode Gaussian beam,the intensity of transmitted polarizing light oscillates periodically with one of the three parameters,i.e.the incident angle at the interface of the cementing layer,the thickness and the refractive index of the cementing layer,and the shape of transmitted beam will be changed.Comparatively,the effect of prism on o light is less than a light.But in general,the effect on the transmitted Gaussian beam is lessthan 1%.
