Abstract

In this paper an analysis of the energy extraction from the amplifying medium is given for the case of quasi-stationary nonlinear losses of radiation. The general expressions found for the extraction coefficient became a basis for a detailed analysis of the energy extraction from the medium with losses proportional to the radiation intensity. The influence of parameters of both medium and the pulse (so far as the length and the shape of the latter is concerned) on the extraction efficiency was shown, and the conditions under which the efficiency is maximal were determined. The results of experimental examinations of the extraction coefficient dependence upon the length and energy of the pulse and upon the amplification coefficient in the system of neodymium glass amplifiers are presented.
