Abstract

The application of an amplifying module developed for a pulse-periodic amplifier as an active medium of a pulse-periodic continuous-wave laser radiation generator is considered. The created computer model of such a generator is described. The results of computational experiments are presented. It is shown that in this generator in the free-running mode it is possible to obtain more than 80% of the pump energy conversion into coherent radiation of the generator.
