A UV-grade silica optical fiber was pumped by a 281.8 nm XeBr excimer laser. The first Stokes spectrum was observed at 285 nm. The spectral width was one half of that of the spontaneous Raman spectrum. A numerical analysis of stimulated Raman scattering which includes two-photon absorption loss is presented. The Raman-gain coefficient was determined by the analysis of observed nonlinearity in Stokes output and was found to be 1.8 x 10/sup -5/ cm/MW. It was also shown that two-photon absorption is a more important loss factor than linear attenuation. The shortest limit of wavelength for amplification by stimulated Raman scattering is also discussed.
