摘要：

The propagation dynamics of symmetric Pearcey-Gaussian beam embedded with on-axis and off-axis optical vortices (OVs) is investigated. Based on the extended Huygens-Fresnel diffraction integral, influences of embedded location, the off-axis distance and topological charge (TC) of OVs on the autofocusing dynamics of the symmetric Pearcey-Gaussian vortex beam (SPGVB) are explored analytically and numerically. The results show that, the embedded location, the off-axis distance and TC of OVs can significantly affect the initial intensity distribution, the propagation trajectory, the autofocusing length and the peak intensity at the focal plane. Interestingly, the fitted expression describing the relationship between the peak intensity of SPGVB and the off-axis distance of OVs with different TC is obtained, which would provide a method to determine the off-axis distance or the TC of OV based on the intensity distribution. The results indicate that SPGVB holds potential applications in biomedical treatment, optical manipulation and optical communication. © 2022
