无衍射贝塞尔光束的传输调控研究进展（特邀）

Abstract

Significance The invention of lasers has led to a boom of laser technology in various science and engineering of many interdisciplinary fields, which have been widely applied in optical manipulation, precision measurement, optical communication, laser processing, microscopy imaging, and so on. However, the simple propagation characteristics of the traditional Gaussian laser mode have hit the bottleneck in the further development of laser technology and failed to meet the everincreasing needs in the related fields. Consequently, light field manipulation has emerged. By modulating the amplitude, phase, and polarization of the light field, many new types of spatially structured fields with novel physics effects or propagation properties have been proposed. Optical vortices and cylindrical vector beams are among the most
