Paper Abstract

An approximate analysis of an output power in two-mirror lasers and distributed feedback lasers is presented. The approach is based on the semiclassical theory. It includes gain saturation effects, non-linear dispersion effect, and spatial hole burning effect. The spatial field dependence of the laser modes is taken into account. Using energy theorem and the threshold field approximation an expression relating the small signal gain to the output power and system parameters is obtained. The laser characteristics obtained reveal an optimal coupling strength providing maximal power efficiency of the systems as a function of the structure parameters. The results obtained are found to be in good agreement with the exact solutions and experiment.
