Abstract

This paper presents a study of astigmatic structured Laguerre-Gaussian beams (asLG) and their orbital angular momentum (OAM). The complex amplitude of the asLG beam is obtained, which takes into account the distance along the z-axis after the cylindrical lens, as well as the angle of inclination of the cylindrical lens. An expression for the OAM is obtained that depends only on the Hermite-Gaussian mode amplitudes. Computer modeling has been carried out, which is in good agreement with experiment.

散像结构拉盖尔-高斯光束：轨道角动量及其变换

本文研究了像散结构拉盖尔-高斯光束及其轨道角动量。考虑圆柱透镜后沿z轴的距离和圆柱透镜的倾斜角，得到了asLG光束的复振幅。得到了仅依赖于厄米-高斯模态振幅的OAM表达式。计算机模拟结果与实验结果吻合较好。
