Abstract: It is shown that the use of misalignment and a divergent incident beam in a double-pass Nd : YAG amplifier of a master oscillator – amplifier system used in ranger finding makes it possible both to increase the output pulse energy and to improve the output beam quality. The misalignment suppresses the amplifier selfexcitation caused by a finite contrast of the output polariser. The use of a divergent incident beam allows one to increase the efficiency of energy extraction from the amplifier and to decrease the vignetting effect. The experimental results agree with the results of numerical simulation.

Keywords: laser amplifiers, solid-state lasers, laser beam characteristics.
