WebAug 25, 2024 · Stimulated Brillouin Scattering (SBS) is the strongest third order nonlinearity and plays an important role in contemporary science and applications, particularly lasers, communications, fiber optics and basic physics. Brillouin scattering (also known as Brillouin light scattering or BLS), named after Léon Brillouin, refers to the interaction of light with the material waves in a medium (e.g. electrostriction and magnetostriction). It is mediated by the refractive index dependence on the material properties of the medium; as described in optics, the index of refraction of a transparent material changes under deformation (compression-distension or shear-skewing).
