Displacements and evolution of optical vortices in edge-diffracted Laguerre-Gaussian beams
Aleksandr Bekshaev, Aleksey Chernykh, Anna Khoroshun +1
Based on the Kirchhoff-Fresnel approximation, we consider behavior of the optical vortices (OV) upon propagation of the diffracted Laguerre-Gaussian (LG) beams with topological cha…

Evolution of the phase singularities in edge-diffracted optical-vortex beams
Aleksandr Bekshaev, Lidiya Mikhaylovskaya, Aleksey Chernykh +1
We study, both theoretically and by experiment, migration of the amplitude zeros within a fixed cross section of the edge-diffracted optical-vortex beam, when the screen edge perfo…
