Abstract

In this paper, we studied the transmission characteristics of a Bessel Gaussian beam (BG) carrying a rotational asymmetric power-index phase vortex (PEPV-BG), and explored its propagation characteristics in free space through theoretical analysis and numerical simulation. The numerical simulation results show that by modulating the topological charge(TCs) and power index(PIs) of the PEPV-BG beam, the intensity and phase of the beam are redistributed. This type of intensity distribution based on changes in the topological charge and PIs has applicable in particle capture, light capture, and biopharmaceutical sectors.
