Synthesis of optical vortices by technique of a phase wedge

It is advanced a two-dimensional model for investigation of spatial dynamics of stationary light fields with disruption of a wave front including optical vortices or with pronounced amplitude inhomogeneity. Theory of synthesis of optical vortices in a Gaussian beam by an optical wedge is developed. Optimum wedge parameters for high efficiency generation of a light beam with perfect optical vortex are found by use of the computer simulation.
