Abstract
Stimulated Brillouin scattering (SBS) and wave front phase conjugation of CO2 laser radiation in compressed xenon placed into low Q resonator of this same laser has been demonstrated experimentally for the first time. The action on nonlinear medium was carried out by opposing focused beams of multimode radiation. The difference in resonator longitudinal mode frequencies was set equal to the frequency of the acoustic wave excited by the radiation with 9.584 micrometers wavelength at SBS. Radiation pulse duration was close to acoustic phonon lifetime. In experiments the SBS excitation was manifested longitudinal mode synchronizing, power and energy rise and also in increasing laser radiation oscillation duration and in decreasing divergence to diffraction limit.
