Paper Abstract

In contrast to the traditional spectroscopic techniques, the picosecond stimulated Raman scattering (SRS) in fibers permits one to determine the anharmonicity constants for silica tetrahedron vibrations and local dopant vibrations. The results of new experiments using the technique of picosecond SRS excitation in pure and doped silica fibers are presented. Apart the fundamental Raman-active silica and dopant vibrations and their overtones the intense combination bands were detected. The comparative studies of undoped and erbium-doped silica fibers were made. When the photoinduced changes took place in a silica fiber core the distinct combination SRS bands were observed, whereas the presence of an erbium ions in silica network didn't disturb the SRS bands originated from silica tetrahedron vibrations.
