Short-pulse generation by saturated KrF laser amplification of a steep Stokes pulse produced by two-step stimulated Brillouin scattering

Abstract

We propose a new method for generating short laser pulses. It consists of generation of steep pulses and saturated amplification. A steep Stokes pulse created by two-step stimulated Brillouin scattering is amplified with a KrF laser under conditions of strong saturation. Pulse shortening by approximately 40% is achieved by amplification.
