Paper Abstract

Phase- and polarization conjugation has been realized by phase locking and phase conjugating two linearly polarized components of a depolarized beam by means of stimulated Brillouin scattering in nitrogen at 75 bar. Hereby, depolarization losses of an oscillator-amplifier laser system have been reduced from 36% without polarization conjugation to 7.1% with vector phase conjugation. An application in a novel oscillator double- amplifier laser system is presented where the amplifiers are operated in a parallel arrangement. An average of 81 percent of the total optical energy generated in the system has been transferred into the output beam with a beam quality of M2 < 1.1 and excellent pointing stability.
