Ultra-short pulses propagation through a strongly scattering medium

Abstract Forward light scattering of femtosecond pulses through strongly scattering media is investigated experimentally and numerically. The temporal separation between ballistic light and scattered light is exhibited and used to perform optical depth measurements up to 22, corresponding to transmission factor of about 10-9. Quantitative comparisons between experiments and Monte Carlo simulations show a good agreement. Computations are based on a semi Monte Carlo method including polarization effects. Temporal forward scattered light evolutions with concentration and particle size are presented
