Paper Abstract

An opportunity to compensate phase and polarizing distortions of the laser radiation directly in Nd:GGG active medium and also in phototropic LiF:F2- crystal is investigated. We found that an application of modified Sagnac interferometer with passive LiF:F2- Q- switcher, located inside it, allows not only to increase stability and power of laser pulses, but also to narrow the laser oscillation spectrum. The possibility is demonstrated of generating single-mode radiation with an energy in a train of laser pulses higher than 7 J, a peak power of a single pulse in a train up to 50 kW, the spatial brightness exceeding 5 x 1010 W/cm2 x sr, and the coherence length in excess of 13 m.
