摘要：

Stimulated Brillouin scattering (SBS) provides a simple and effective method to compress pulses to 100 ps for shock ignition. This paper gives out two kinds of novel SBS mediums with excellent quality and superior performance, FC-43 and FC-70. The SBS parameters of FC-43 and FC-70 are calculated and measured. Both of these two mediums have the properties of lower absorption, higher optical loads and short phonon lifetime. The shortest pulse width achieved by SBS compressor was 235 ps for FC-43 and 175 ps for FC-70, and the highest energy reflectivity was more than 80 % for both of them. The compression efficiency and stability of FC-70 is better than FC-43, indicating FC-70 is more suitable to be used as the SBS medium to generate 100-ps pulses.
