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…
Paraxial Light Beams with Angular Momentum
A. Bekshaev, M. Soskin, M. Vasnetsov
Fundamental and applied concepts concerning the ability of light beams to carry a certain mechanical angular momentum with respect to the propagation axis are reviewed and discusse…
