| 摘 要： | 在强激光放大系统中,使用C_3H_6O作为非线性介质,获得了高效的SBS效应,Stokes波一次反射率～60％,末级激光放大器对Stokes波的能量放大率达到3,Stokes波脉宽压缩率为4,功率放大系数达到12,经SBS后,激光近场强度分布得到明显改善,在强泵浦下,Stokes波了现高频调制。对实验结果及其应用前景进行了讨论。

| Abstract: | A study of stimulated Brillouin scattering in C_3H_6O for an intense laser amplifier system was made, The threshold of SBS is 0.15j (pulse dura- tion 3ns). Stokes wave reflected efficiency 0.60, the energy amplification factor about 3,and power amplication factor 12 were obtained in experiment. Phase aberration of input laser beam was also corrected by SBS. The experimental results and its applicability were discussed. |
