High intensity pulse generation by saturated amplification of Stokes pulse with steep leading edge

摘要

We have developed a new technique for high intensity short pulse generation. It consists of a steep pulse generation and a saturated amplification. Stimulated Brillouin scattering by a broad-band oscillator pulse was used to generate the steep Stokes pulse. The Stokes pulse was amplified by discharge type KrF laser amplifier under strongly saturated condition. The pulse shortening by the amplification was confirmed.
