Elliptical Airyprime Vortex Beam

Abstract

We introduce a novel family of elliptical Airyprime vortex beams (EAPVBs) utilizing both numerical simulations and experiments. The inconsistency in convergence speeds of the long and short axes similarly affects the EAPVB, which focuses automatically twice during the propagation process. Though altering elliptical parameters modifies the EAPVB's maximum normalized intensity, it has minimal effect on the position of the maximum normalized intensity point. As the EAPVB propagates, its vortex becomes disrupted, and its maximum normalized intensity can exceed that of CAPVB when elliptical parameters is near 0.98. The EAPVB's maximum normalized intensity and its position minimally change with altered topological charges. In this paper, we demonstrate how to construct EAPVB as a tunable optical bottle, which is used as experimental tool for capturing particles. These findings have considerable potential for applications in optical communication and particle capture.
