Abstract

We have analyzed theoretically the dependence of lasing threshold and efficiency of laser crystals powders on the sample thickness, the volume fraction occupied by the particles and the mean particle size. The optimal range of these parameters that minimize the threshold and maximize the efficiency has been determined.
