Abstract
In this paper we present a general approach to determine the stability of a laser cavity which can include nonconventional phase transformation elements. We consider two pertinent examples of the detailed investigation of the stability of a laser cavity firstly with a lens with spherical aberration and thereafter a lens axicon doublet to illustrate the implementation of the given approach. In the particular case of the intra–cavity elements having parabolic surfaces, the approach comes to the well–known stability condition for conventional laser resonators namely 0 (1 / 1 )(1 / 2 ) 1. ≤ − z /R1 − z/ R2 ≤ The method can be considered as a technique for intra–cavity beam shaping.
