In invention is solved the problem of power laser polarization control. For this purpose there are conditions, at which the mode of switching between laser orthogonal polarizations is realized. In order to the switchings of polarization were periodic, it is necessary to change periodically the optical resonator length with the help of piezoceramic or any other drive unit. The switching of polarization states occurs during pulsing laser pumping also at the expense of heating, pressure variation and laser mix charge. Passing laser output beam through the Bruster plate, it is possible to received two impulse-periodic beams, dephased on 180⁰.
