Among the most fascinating phenomena related to light travelling in random materials, weak localization of light is the most robust interference effect, taking its strength in the reciprocity of Maxwell equations. Since it is strictly related to the well-defined wave character and to the preservation of the optical information, so far, it has been proposed for the case of elastic multiple scattering only. Here we demonstrate that weak localization of light can survive also in the inelastic scattering regime. This new finding represents the first experimental evidence of an interference effect in spontaneous Raman scattering on a macroscopic scale.
