Analysis of Polarization Dynamics in Laser-Induced Optical Vortices for Advanced Beam Shaping Applications

The study of optical vortices and their polarization dynamics has gained significant
attention due to their application in advanced optical technologies. Optical vortices, characterized
by their unique polarization states, are generated through the manipulation of light’s orbital angular
momentum (OAM). This research explores the generation and manipulation of optical vortices
using novel techniques, such as plasmonic metafibers and mode conversion, to create pulsed
polarized vortex beams (PVB). These beams exhibit advanced characteristics that enhance laser
processing, surface excitation, and high-speed communication systems. The study aims to
understand the effects of polarization dynamics on vortex formation and to develop efficient
methods for controlling these dynamics. The findings demonstrate how variations in
spatiotemporal properties, such as the offset of splicing and the period of metafibers, influence the
performance of pulsed PVB. This research opens new avenues for designing and controlling laser
systems with specialized beam properties, contributing to fields like optical communications,
medical imaging, and materials processing.
