摘要
基于广义斯托克斯参量, 推导出了部分相干部分偏振高斯谢尔模型(GSM)电磁束通过光阑透镜后交叉谱密度矩阵、光强、偏振度、偏振椭圆的方位角及椭偏角的解析表达式, 并用以研究菲涅耳数、自相关和互相关长度以及束腰宽度对焦移和偏振特性的影响。对主要数值计算结果做了物理解释。
Abstract
Based on the generalized Stokes parameters,analytical expressions for the cross-spectral density matrix,intensity,degree of polarization,orientation of the polarization ellipse and ellipticity angle of partially coherent partially polarized Gaussian Schell-model(GSM) electromagnetic beams propagating through an aperture lens are derived,which are used to study the effect of Fresnel number,self- and cross-correlation lengths and waist width on the focal shift and polarization properties.The main numerical calculation results are interpreted physically.吕百达|baidalu0@tom.com
