使用非线性四波相互作用光谱方法记录了七种在受激布里渊散射（STBS）中活跃的液体的声共振光谱，其频率对应于激光辐射在钕玻璃中的反向散射。这些测量使得可以在同一实验中确定 STBS 增益以及液体中超音速的衰减时间和传播速度。
The method of nonlinear four-wave interaction spectroscopy was used to record the spectra of acoustic resonances of seven liquids active in stimulated Brillouin scattering (STBS) at frequencies corresponding to the backscattering of laser radiation in neodymium glass. These measurements made it possible to determine in the same experiment the STBS gain and the decay time and velocity of propagation of hypersound in the liquids.
