摘要

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。

Astigmatic Structured Laguerre-Gaussian Beams: Orbital Angular Momentum and Its Transformation

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.

期刊介绍： The journal covers a wide range of issues in information optics such as optical memory, mechanisms for optical data recording and processing, photosensitive materials, optical, optoelectronic and holographic nanostructures, and many other related topics. Papers on memory systems using holographic and biological structures and concepts of brain operation are also included. The journal pays particular attention to research in the field of neural net systems that may lead to a new generation of computional technologies by endowing them with intelligence.
