High-angle diffraction of a Gaussian beam by the grating with embedded phase singularity
A. Bekshaev, O. Orlinska, M. Vasnetsov
Spatial characteristics of the optical-vortex (OV) beams created during the Gaussian beam diffraction by a grating with groove bifurcation are analyzed theoretically and numericall…

Structure of optical vortices produced by holographic gratings with "fork" geometry: Kummer beams
A. Ya. Bekshaev, A. I. Karamoch, M. V. Vasnetsov +2
Holographic gratings with topological defects (branching of one or more fringes) are widely used for generating light beams with optical vortices (OV). This work presents an analys…
