Abstract

In this paper, we show that spontaneous emission at input signal ∼0.1-1 W/cm² does not lead to self-excitation of amplifiers whereas parasitic reflections of laser radiation can be very dangerous. The laser beam brightness and high phase conjugated quality in the focussed beam depends on coefficient R of parasitic diffuse reflections from amplifiers windows and selector lenses. The effective operation of laser facility occurs at R≥10^-7.
