摘要

本文利用分数阶傅里叶变换研究了一组自动聚焦激光束的传播轨迹变化。考虑了由类似棱镜的偏转光束的相位函数补充的位移有界的airy -高斯光束簇。漂移和相位偏差(根据载波空间频率)使得改变一组自动聚焦光束的传播轨迹成为可能。通过数值模拟研究了所考虑的参数对一束Airy-Gaussian光束的自动聚焦特性的影响。

Changing the trajectory of Airy beam sets with spatial carriers

In this paper, we study a change in the propagation trajectory of a set of autofocusing laser beams using a fractional Fourier transform. Clusters of displaced bounded Airy-Gaussian beams supplemented by a phase function that deflects the beam similarly to a prism are considered. The shift and phase deviation (according to the carrier spatial frequencies) make it possible to change the propagation trajectory of a set of autofocusing beams. The influence of the parameters under consideration on the properties of autofocusing of a cluster of Airy-Gaussian beams is investigated by means of numerical simulation.
