Abstract

We analyze the interaction and the competition of a set of transverse cavity modes. The laser exhibits coexistence among different stationary spatial patterns. These structures display the presence of phase singularities analogous to the vortex structures known in such fields as, for example, hydrodynamics, superconductivity, superfluidity. These singularities are arranged in the form of regular arrays, and the equiphase lines of the field exhibit a notable similarity to the field lines of the electrostatic field generated by a correspoding set of point charges.
