摘要
根据光在格兰-泰勒棱镜和格兰-傅科棱镜空气隙胶合层中的干涉效应,分析了空气隙偏光镜对不同束腰半径的单模高斯光束光强分布的影响.结果表明:对于某一波长的入射光,束腰半径越小,光强分布受偏光镜的影响越明显;另外,随着束腰半径的减小,高斯光束的形状也会发生变化.比较而言,格兰-泰勒棱镜产生的影响要小于格兰-傅科棱镜,这说明前者的综合性能优于后者.
Based on the interference effect of Glan-Taylor prisms and Glan-Foucault prisms air-gap cementing layer, the transmitting characteristics of deferent girding radios single mode Gaussian beam striking on polarizing prisms are analyzed. The result shows, for certain wavelength light, less girding radios will result in more influence on light intensity distribution and the shape of Gaussian beam will change when the girding radios get less. In addition, the influence of Glan-Taylor prisms is less than Glan-Foueault prisms. In general, the synthesis performance of the former is better than the latter.
