In highly scattering media, interference effects can result in Anderson localization. In this regime where stationary solutions of the wave equation were spatially localized modes, it was discovered that the amplitude modulation observed in the speckle pattern in the presence of a Kerr nonlinearity was the result of the beating between the excitation frequency and the eigenfrequency of a localized mode of the random medium. In fact, the nonlinearity preferentially transfers the energy from the pump into the localized modes of the system, which provide natural resonant cavities.
