Dynamic instability of speckle patterns in nonlinear random media

Not Accessible

Your library or personal account may give you access

Abstract

Linear stability analysis is performed of speckle pattern resulting from multiple, diffuse scattering of coherent light waves in random media with intensity-dependent refractive index (noninstantaneous Kerr nonlinearity). The speckle pattern is shown to become unstable with respect to dynamic perturbations within a certain frequency band, provided that the nonlinearity exceeds some frequency-dependent threshold. Although the absolute instability threshold is independent of the response time of the nonlinearity, the latter significantly affects speckle dynamics (in particular, its spectral content) beyond the threshold. Our results suggest that speckle dynamics becomes chaotic immediately beyond the threshold.
