The improved successive iteration flowchart of both forward and backward codes is proposed, in which the effects of fabrication imperfections and obscurations of optical components, stochastic phase fluctuations and irradiance-dependent nonlinear index of refraction of active medium, all are important issues central to the design of high-power multipass laser systems, are considered. Typical numerical results for the four- and two-pass amplifier systems often used in practice are given to illustrate the application of our method.
