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.
