Abstract
Nonlinear disordered media uniquely combine multiple scattering and
second-harmonic generation. Here, we investigate the statistical properties of
the nonlinear light generated within such media. We report super-Rayleigh
statistics of the second-harmonic speckle intensity, and demonstrate that it is
caused by the mesoscopic correlations arising in extreme scattering conditions.
The measured conductance is the lowest ever observed in an isotropically
scattering 3D medium, with applications in broadband second-harmonic
generation, wavefront shaping in nonlinear disordered media, and photonic
computing.
