Diffuse waves in nonlinear disordered media

Published 2003-03-07Version 1

We review our recent theoretical results on multiple scattering of waves in nonlinear disordered media. In particular, we discuss angular correlations of scattered waves, coherent backscattering cone, and the new phenomenon of temporal instability of multiply scattered waves in disordered media with sufficiently strong nonlinearity. Instability threshlod is derived, dynamics of speckle pattern beyond the threshold is discussed.
