Abstract

The effect of a radially varying gain in tightly focused lasers is investigated with a generalized ABCD matrix formalism in a nonparabolic approximation. It is shown that the beam sizes can differ strongly from the theoretical with a constant gain or with radially varying gain in a parabolic approximation. Geometrical threshold zones are defined and studied and, instead action for a given cavity design.
