Abstract
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.
