Pattern selection in wide aperture lasers is provided by active sources of traveling waves. Finite absorbing transverse boundaries select near-field lasing patterns from a one-parameter continuous family of allowed modes. The selected pattern on the boundary invades the interior consuming any spiral waves that are formed in this region. As a result, only simple stationary patterns are established in nonstiff lasers.
