Abstract

In this paper, we elaborate the analytical propagation expression for a double-half inverse Gaussian hollow beam (DHIGH) in a uniaxial crystal perpendicular to the optical axis, and the normalized intensity characteristics and the phase pattern of this optical field are analyzed with several numerical calculations. It is demonstrated that the intensity of the DHIGH beam exhibits astigmatism, with its evolution upon propagation being highly influenced by the initial beam’s diameter and the refractive index ratio of the anisotropic crystal. The finding could contribute to the advancement of hollow beams in anisotropic media.

双半反高斯空心光束在单轴晶体中的演化特性

本文给出了双半反高斯空心光束（DHIGH）在垂直于光轴的单轴晶体中的解析传播表达式，并通过数值计算分析了该光场的归一化强度特性和相位图。结果表明，DHIGH光束的光强表现出像散现象，其光强在传播过程中的演变受光束初始直径和各向异性晶体折射率比的影响较大。这一发现有助于推进各向异性介质中空心梁的研究。
