PRECISION OF CONTROL OF THE ANGULAR-DISTR IBUTION OF RADIATION FROM ANEODYMIUM GLASS-LASER WITH PHASE-CONJUGATION AND AN INTRACAVITY SPACE-TIME LIGHT-MODULATOR

A description is given of a method and the experimental results are re ported of an investigation of the precision of control of the angular distribution of radiation in a laser amplifier with phase conjugation coupled to a master oscillator with an intracavity light-controlled sp acetime modulator. It is shown that the precision of control in the di rection of radiation is at least 0.3 of the diffraction divergence of a beam and the response time of the modulator to a control signal is 5 00 mus. The results are given of a study of the precision of phase con jugation of radiation by double reflection from stimulated Brillouin s cattering mirrors, including results obtained under conditions simulat ing self-interaction of radiation.
