摘要
设计了一种基于受激布里渊散射(stimulated Brillouin scattering,SBS)的非共线多泵浦百皮秒放大方案,通过模拟和实验验证了介质参数对非共线组束放大过程的影响。结果表明能量提取效率会随着介质的增益系数的增加而显著增加;当选择的介质为HT-70时,压缩后的脉宽为930.4 ps,种子光能量为135.1 mJ。当3束泵浦光总能量为973 mJ时,能量提取效率达到最大,最大值为36.71%,种子光放大后的最终脉宽为877.3 ps,波形良好且无拖尾。
A non-collinear multi-pump hundred picoseconds amplification scheme based on stimulated Brillouin scat-tering(SBS)was designed,and the effect of medium parameters on the non-collinear group amplification process was verified through both simulation and experiments.The results show that the energy extraction efficiency significantly increases with the increase of the medium's gain coefficient.When the selected medium is HT 70,the compressed pulse width is 930.4 ps,and the seed light energy is 135.1 mJ.When the total energy of the three pump beams is 973 mJ,the energy extraction efficiency reaches the maximum,with a maximum value of 36.71%,and the final pulse width after seed light amplification is 877.3 ps,with good waveform and no tailing.
