Solution of the inverse of high-power multi-pass amplifier with improved successive iteration method

The successive iteration method to solve the inverse problem of high-power multi-pass amplifier system is proposed,in which the effects of fabrication imperfection and obscuration of optical components and B integral are considered.The flow chart of calculation codes is shown.Two-pass amplifier system has been taken as a typical example to illustrate the application of the method.The inverse problem of two-pass amplifier has been studied.
