Abstract

The analytical model of caustics of multimode asymmetrical beam absorbed in active medium was developed. There were found criteria of optimum waist location and optimum Rayleigh range in dependence on absorption length of active medium and parameters of pumping beam. There was shown that the diode beam forming optics satisfying the condition of optimum pumping should equalize the Rayleigh ranges in vertical and horizontal directions. The results of optimization were qualitatively confirmed in experiment with Nd:YAG laser end pumped by highly asymmetric beam of 2 W diode laser.
