Abstract
Transverse pattern dynamics in the output of a laser are studied by numerical solution of the Maxwell Bloch equations. It was found that simple patterns involving many radial and angular modes can be simply described in terms of the motion and interaction of defects, singularities in the complex field. The complexity of the patterns and dynamics increase as the Fresnel number of the resonator is increased and as the mode spacing, gain, and cavity detuning are adjusted to bring more modes within the range of frequencies where gain exceeds loss.
