Usually, the effect of lateral shift of reflected (or transmitted) light from the interface separating two media, known as the Goos-Hänchen effect (GHE), has been studied in linear optics for two-wave processes [1]. 

Here, I will present our results of phenomenological and numerical analysis of GHE for inelastic light scattering by acoustic phonons [2] and by magnetostatic waves in the Damon-Eshbach configuration [3], i.e. for three-wave interactions.
