摘要
基于有扭曲的各向异性高斯 谢尔模型 (AGSM)光束二阶矩矩阵的传输公式 ,研究了AGSM光束通过透镜的聚焦。作了详细的数值计算 ,说明聚焦AGSM光束的传输特性 ,包括光束参数和横向光强的变化 ,特别是扭曲项和空间相关长度对聚焦特性的影响。
Based on the propagation law of the second-order moments matrix,the focusing of twisted anisotropic Gaussian-Schell model (AGSM) beams through a lens is studied.Detailed numerical results are presented to illustrate the propagation behavior of focused AGSM beams,including the evolution of beam parameters and the transversal intensity.In particular,the influence of twist term and spatial correlation length on their focusing properties is analyzed.
