Abstract

Properties of laser cavity composed of two plane segmented mirrors placed at half-Talbot distance are considered theoretically in application to gas laser with annular active medium. Discrimination of in-phase mode against other supermodes is demonstrated. For saturable gain model, a critical small gain is found for which the in-phase mode become unstable.
