FIELD: laser technology. ^ SUBSTANCE: amplifier has pumping unit, master generator, active element and system of laser radiation reflectors coming in the form of rotary optical reflecting elements, first dummy mirror installed to secure possibility of at least one additional amplifying transition of radiation of master generator and stable optical resonator incorporating second dummy mirror, output semitransparent flat mirrors and diaphragm for selection of lateral modes. Optical axis of optical resonator of master generator and axis of radiation beam of master generator passes through first butt of active element at certain angle to longitudinal symmetry axis of active element. Output semitransparent flat mirror is mounted for sequential optical alignment by means of rotary optical reflecting elements through second butt of active element with first dummy mirror to ensure possibility of first amplifying transition of radiation of master generator crossing optical axis of optical resonator of master generator at angle satisfying certain condition. ^ EFFECT: enhanced reliability and efficiency of amplifier. ^ 12 cl, 6 dwg |
