摘要

本文提出了具有像散相位的对称皮尔斯高斯涡旋光束（APSPGVB），并研究了其在自由空间中的传播特性。APSPGVB由一个高斯项、一个涡项、一个像散相位因子和两个乘法皮尔斯积分组成，并由四个不同的因子调制。结果表明，通过改变不同的因素，可以改变APSPGVB的焦距和焦强度。此外，通过选择适当的参数，与初始平面的光场最大强度相比，焦强度可以变化10到165倍。我们相信这一结果为粒子操纵和其他光学应用提供了良好的前景。

Symmetric pearcey gaussian vortex beams with the astigmatic phase

In this letter, we present the symmetric Pearcey Gaussian vortex beam with the astigmatic phase (APSPGVB) and investigate its propagation properties in free space. APSPGVB, which consists of a Gaussian term, a vortex term, an astigmatic phase factor, and two multiplicative Pearcey integrals, is modulated by four different factors. The results show that the focal length and the focal intensity of the APSPGVB can be altered by modifying the different factors. Furthermore, the focal intensity can vary from 10 to 165 times compared to the maximum intensity of the optical field in the initial plane by selecting appropriate parameters. We believe the results present excellent prospects for particle manipulation and other optical applications.
