OBSERVATION OF ANOMALOUS TRANSPORT OF STRONGLY MULTIPLE SCATTERED-LIGHT IN THIN DISORDERED SLABS

We present results of experiments on the transport of light through th in random media. Total transmission and time-resolved propagation meas urements were performed using strongly scattering samples of varying t hickness L. For L/l < 8, where l is the transport mean free path, the observed decay times from the long-time exponential behavior exhibit s trong deviations from diffusion theory and radiative transport theory, whereas the total transmission measurements do not. For the thinnest sample (L/l similar or equal to 2) a reduction of the diffusion coeffi cient with a factor of 2 was observed.
