Abstract

In this paper propagation of beams from positive branch confocal unstable resonator through turbulent atmosphere is investigated numerically. It was assumed that the resonator has one variable reflecting mirror in one end and an ordinary uniform reflecting mirror in the other end. Using Huygens-Fresnel integral and iteration method, the dominant transverse mode of the resonator in near field was calculated. Then by using extended Huygens integral, the propagation of fully coherent output beam of the resonator through turbulent atmosphere was evaluated. The effects of resonator characteristics and the atmospheric turbulence parameter as well as propagation distance on the propagated beam were investigated.
