Abstract
The tilted-wave solutions of the laser Ginzburg-Landau equation which describes the dynamics of class-A lasers are investigated. The excitation of tilted waves is shown to result in standing-waves patterns in the form of stripes and/or of vortex lattices. The most stable structure is a tilted wave, the square vortex lattice is less stable in unbounded space. The stripe-structure and square vortex lattices in real lasers are predominantly due to lateral boundaries. The laser parameters for spatially symmetric lattices and for nonsymmetric structures dominated by tilted waves are determined.
