| Abstract: | The results of a simultaneous account of the influence of the amplifying properties of an active medium of a laser amplifier and its inhomogeneities on energy characteristics in an application zone are given. An intensity is described to the approximation of linear and saturated gain. Distortions in the active medium are accounted for by the wave front dispersion. A simultaneous account of inverse indices and optical quality has allowed determination of an optimal number of amplifying stages of a laser unit providing the maximum radiation power density in the application zone.Institute of Mechanics, St. Petersburg, Russia.
