We report efficient amplification of weak femtosecond supercontinuum pulses by a stimulated Raman scattering process in pressurized H(2) gas excited with 350-fs-duration frequency-doubled pulses from a regenerativeamplified Ti:sapphire laser. An amplification factor of 10(9) is obtained at the wavelength of 465 nm for seed pulses produced by supercontinuum generation in glass.

The methods of "dry" synthesis of Ag-AgI hybrid nanostructures in the bulk of nanoporous silica glass with an average pore size of 17 nm have been described. Spectral characteristics of obtained nanocom posites have been presented. The possibility of forming the Fano resonance due to the electromagnetic cou pling between AgI excitons and Ag plasmons has been shown.
