We examine theoretically and experimentally the transverse intensity profile of a laser beam as it traverses through a turbid medium. By increasing the concentrations of milk in an aqueous solution we examine the transition from the weakly scattering to the diffusive regime. The experimental data of the transverse beam profiles for various scattering strengths are obtained in a non-contact geometry from digital images of the exit surface of the medium. The intensity distributions are compared with theoretical data obtained from Monte Carlo simulations.
