Introduction. Stimulated Brillouin scattering (SBS) effect is a third-order nonlinear effect, which is produced by the interaction of photons with phonons in the medium [ 1 – 3 ]. The SBS effect can be exploited to realize the conversion from optical waves (with higher frequency) to acoustic waves. Stimulated Brillouin scattering occurs when a beam of laser light generates a parametric process that simultaneously produces an exactly retroreflected Stokes beam and an acoustic wave traveling in the forward direction. Energy conservation requires that the Stokes beam frequency is reduced from the laser frequency by the frequency of the . Song, J. et al.
