Vortex ring reconnections in elliptic Gaussian beams

Not Accessible

Your library or personal account may give you access

Abstract

We study theoretically accessible optical vortex rings and their topological transformations in superpositions of elliptic and astigmatic Gaussian beams with a plane wave. We demonstrate the birth and death of vortex rings at isolated points on and off the optical axis and their pairwise and higher-order three- and four-ring reconnections.
