Transverse pattern development, phase vortex formation, and space-time dynamics in a laser model not restricted a priori to a few modes

Transverse pattern dynamics in the output of a laser are studied by detailed numerical solutions of the full set of Maxwell Bloch equations. The effects of different parameters on the behavior of the solutions are investigated. Our numerical results reveal a rich variety of behaviors in the pattern evolution, phase vortex formation and spatiotemporal dynamics in the output of a laser beam.
