摘要
为了提高双池受激布里渊散射(SBS)系统的能量转换效率和负载能力,在布里渊放大池和产生池中选用布里渊频移接近的不同介质,利用Nd∶YAG调Q激光对其特性进行了实验研究。与同种介质的双池系统相比,不仅能保持足够的能量转换效率,而且能够有效地提高其负载能力和稳定性。分析和讨论了双池间距对受激布里渊散射性能的影响。
Abstract
In order to enhance the energy conversion efficiency and the power-load of two-cell stimulated Brillouin scattering (SBS) system, different liquid SBS mediums with almost similar Brillouin frequency shifts are used in the generator cell and the amplifier cell. The characteristics of the SBS system are investigated experimentally with Nd∶YAG Q-switched laser. Compared with two-cell SBS system with the same liquids, it can not only keep enough high-energy conversion efficiency, but also can effectively improve the system power-load ability and stability. The influences of the distance between the two cells on the SBS characteristics are analyzed in detail.
