摘 要: | 对于窄脉冲激光泵浦双池受激布里渊散射(SBS)系统,其泵浦脉冲宽度和前沿形状以及振放双池系统的参数,都将影响到SBS的脉冲强度与转换效率.实验中采用了两个具有不同前沿的窄脉冲先后相继泵浦双池SBS系统.通过改变SBS放大池和聚焦透镜的焦距,观察到所产生的两个SBS脉冲具有不贩转换效率.利用振荡池产生的SBS调制种子光在放大池中的行波放大对此结果作了分析,由此提供了一种设计双池SBS系统参数的方法.

Two-Cell Stimulated-Brillouin-Scattering Systems Pumped with Narrow-Pulse-Width Laser |

Abstract: | The pumping laser pulse of narrow pulse-width together with its leading edge shape as well as parameters of the two-cell stimulated-Brillouin-scattering (SBS) systems have an influence on the SBS pulse intensity and conversion efficiency. Two narrow pulses with different leading edges pump the two-cell systems simultaneouly. Bu changing the amplifier-cell length and the focal length, different conversion efficiencyies were observed. The two SBS pulses results are analyzed with transient seeded Stockes in the amplifier-cell. A method to design the two-cell systems is proposed. |
