摘要：
The possibility of suppressing the radiation depolarization that appears in the active element of a YAG:Nd3+ laser pumped by linear laser-diode arrays with a pump-pulse-repetition rate of 1 kHz has been experimentally investigated. It is shown that the total suppression of the depolarization of the laser radiation is impeded by the appearance of birefringence in the crystals of the electrooptic shutters and the active medium of the Faraday rotator. This paper discusses the layout of a cavity with beam splitting at the polarization components, which made it possible to obtain an output pulse energy at the second harmonic greater than 10 mJ with intracavity conversion of radiation with a pulse width of 25 ns.
