We describe a phenomenon of nonlinear optics that occurs in the framework of transverse effects and optical vortices in lasers. We find that in a class-B laser vortices can never be at rest, but move, starting from an initial symmetry breaking of the direction of motion, continuously. In a cylindrically symmetric laser this motion will normally be about the laser axis, while in a constant background the motion is toruslike.

Abstract

We describe a phenomenon of nonlinear optics that occurs in the framework of transverse effects and optical vortices in lasers. We find that in a class-B laser vortices can never be at rest, but move, starting from an initial symmetry breaking of the direction of motion, continuously. In a cylindrically symmetric laser this motion will normally be about the laser axis, while in a constant background the motion is toruslike.
