摘要
本文报道了在CCl_4液体中受激布里渊散射的阈值性能.研究了产生受激布里渊散射相位共轭波的阈值是随所用聚焦透镜的焦距,泵浦激光的脉宽和发散角等的变化而变化.实验表明,适当地增加聚焦透镜的焦距,即提高受激布里渊散射的阈值能量可以显著地消除受激布里渊散射与其它非线性效应的竞争.
The threshold behavior of backward Stimulated Brillouin Scattering (SBS) on CCl4 is reported in this paper. The threshold behavior of SBS as a function of foous lenght, pump puls width, and divergence have been investigated. We show that the competing effects between SBS and other nonlinear can be eliminated by increaseing appropriately the fouus length.
