Paper Abstract

In this paper we analyze the losses in coupling radiation from the guide into the free-space and back, for waveguide laser resonator with Gaussian mirror. The laser characteristics showing the behavior of the total coupling coefficient, as a function of the curvature radius, Gaussian parameter and position of the Gaussian mirror are discussed. It is shown that for moderate values of the Gaussian parameter the Gaussian mirror provides transverse mode selectivity in hollow-waveguide structure and minimal coupling losses are obtained for the fundamental laser mode.
