FIELD: quantum electronics. SUBSTANCE: monopulse laser on yttrium aluminium garnet with neodymium has master oscillator, optical amplifier coupled to it through supplementary reflector. Supplementary reflector presents mirror with reversal of wave front. Device composed of linear polarizers and negative lens optically interconnected by means of rotary mirrors enlarging section of radiation beam and guiding the latter into amplifier through master oscillator is placed between master oscillator and amplifier. EFFECT: raised threshold of self-excitation and increased energy output. 1 dwg
