Picosecond pulse generation by stimulated Brillouin scattering compressor

The picosecond pulse was obtained by two-stage stimulated Brillouin scattering (SBS) compressor to compress 8ns laser pulse. The experiment used CCl4 as SBS medium. The laser pulse duratiuon was compressed to 1.5ns by the first stage compressor. In the second compress stage, the experiment investigated the compress procession using 532nm and 1 064nm as puming light separately. The shortest pulse of 60ps was obtained. The results show that the pulse duration shorter than the medium acoustic lifetime can be achieved by SBS compressor.
