摘　　要：本文讨论了受激布里渊散射的阈值效应对后向受激散射光（泵浦光的相位共轭波）线宽、发散角、脉宽、能量集中度的影响，利用其阈值效应可以获得一个面积尽量小的共轭光斑．We discussed the influence of the threshold effect of stimulated Brillouin-scattering on the divergence and line-width of stimulated scattering light, and the light power density of a certain region of target. A point beacon light on a target of far field can be obtained by the means of the threshold effect of stimulated Brilouin-scattering.
