Paper Abstract

An approximate method for the analysis of laser with a saturable absorber, taking into account longitudinal field dependence in the cavity, is presented. An approximate expression relating the small signal gain 2go to the output power normalized to the saturation power in the active medium Pout/Psg, the saturable losses (alpha) so, the ratio of the active medium length to the length of the nonlinear absorber, and to system parameters is derived. The characteristics revealing optimal output mirror reflectivity, which provides optimal power efficiency, are obtained as a function of the system parameters.
