Paper Abstract

Array of fundamental Gaussian beams located on the surface of a hyperboloid of revolution forms a regular net of optical vortices whereas a resulting field represents a singular Bessel-Gaussian beam. A total topological charge of the beam is defined by a phase matching in the beam's array. Such simple key inferences were drawn from our theoretical analysis of light scattering with a stack of optical wedges. We experimentally found out that a Gaussian beam diffracted by a system of dielectrical wedges carried over central-positioned optical vortex, whose topological charge was equal to a number of wedges in the stack.
