Backward Raman amplification in a fused-silica fiber waveguide is studied using two dye lasers for its possible application as an amplifier and a pulse sharpening device. Greater than 90% of pump to signal conversion is observed together with a preferential amplification of the signal pulse front. Short pulse generation and complete pump depletion are also observed in a single dye laser pumped fiber Raman generator-amplifier system.
