Paper Abstract

We show how to synthesize a wave with monochromatic mixed screw-edge dislocation. We obtained theoretically and experimentally that a mixed screw-edge dislocation embedded in a monochromatic Gaussian beam does not propagate as a self- similar stable object, but transforms into several pairs of opposite-sign optical vortices in near field, and produces single-charge optical vortices in far field.
