Abstract
Pattern selection in wide aperture lasers is provided by active source s of traveling waves. Finite absorbing transverse boundaries select ne ar-field lasing patterns from a one-parameter continuous family of all owed 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.
