Simulated Brillouin Scattering (SBS) was used for the temporal compression of single mode Nd:YAG nanosecond laser pulses of 200 to 500 mJ energy. Compression factors of over 10 and energy conversion of 80% in the backscattered SBS beam were regularly obtained. The system consists of a simple SBS oscillator-amplifier setup which avoids the use of pump pulse splitting or pump beam attenuation techniques usually applied in high energy SBS compressors. Resulting SBS pulses were analyzed in the time domain by a fast oscilloscope and a streak camera, in the frequency domain by a pulsed spectrum analyzer. The experimental results were compared with extensive numerical simulations of the SBS-process in the multiple cell setup.
