Stimulated Raman scattering in fibers in the ultraviolet.
Efficient stimulated Raman scattering at 342 nm was obtained in multimode fused-silica fibers pumped by a conventional N(2) laser. The values of the intensity-dependent absorption coefficient and the Raman-gain coefficient were determined: alpha(1), = 3.3x10(-6) cm/MW and gamma = 2.9 x 10(-11) cm/W, respectively. Raman scattering by the OH impurities in the fiber was observed at 385 nm.
