Abstract

We report on experimental and theoretical study of a femtosecond NIR pulse distortion at its propagation in optically turbid medium with highly anisotropic scattering. We have proposed a novel theoretical model of temporal structure of a scattered pulse based on expansion of radiation intensity over orders of scattering. In parallel, we have performed experiments on measuring profile of scattered 50-fs pulse passed a 5-mm slab of model medium with controlled concentration of micron-sized spherical beads. Temporal structure was measured by the means of nonlinear optical gating at noncollinear second harmonic generation. Comparison showed good agreement between experimental and theoretical results and demonstrated validity of the developed theoretical model within wide range of scattering parameters.
