Paper Abstract

Processes of the optic pump energy transformation in system Raman converter-wideband laser medium with homogeneously broadening amplification band have been investigated. Raman converter and wideband medium were used in common cavity. As a Raman converter a barium nitrate and benzol were used, as a wideband media a LiF crystals with F-2 or F2 color centers and oxazyn-1 were used. Thanks to four-levels excitation scheme of the wideband media, pump output excitation threshold of them is less than for SRS excitation. In such system generation start from the widespread medium. The wideband medium amplify seeding radiation of the Raman converter at the Stokes frequencies, which get to the amplification band of the wideband medium. Then, thanks to additional Raman amplification, condensation of the wideband generation spectrum arise. Thus the threshold of the SRS excitation decreased and efficiency of the SRS increased in Stokes or anti-Stokes regions. Under certain conditions in liquid Raman media arise generation on the different types of the vibrations and generation on the combined frequencies too.
