钒酸钇偏光分束棱镜光强分束比的入射角效应
Effect of incident angles on splitting ratio of YVO4 polarizing splitting prisms
摘要
为了分析He-Ne激光斜入射钒酸钇偏光分束棱镜时光强分束比随入射角度的变化关系,根据几何关系、菲涅耳公式及相位匹配条件从理论上推导出光强分束比的数学表达式,通过实验验证,发现理论值和实验值相符合,并对存在的误差进行了分析。这为钒酸钇棱镜在偏光器件中的应用提供了重要的参考价值。
Abstract
In order to analyze the variation relation between light intensity splitting ratio and incident angle with He-Ne laser obliquely incident on YVO4 polarizing splitting prism,the mathematical formula of the light beam were deduced according to the geometric relationship,Fresnel formula and phase matching conditions.Through experimental verification,theoretical value accorded with experimental value,then the error was analyzed.It provides important reference information for the development of YVO4 polarizing splitting prisms as polarizing devices.
