Tam and Zardecki recently developed a radiative transport solution for small angle scattering of a diverging laser beam in a particulate medium. Their solution is extended to the case of a converging laser beam focused in a particulate medium and also to the case of a diverging laser beam which propagates an arbitrary distance through clear air before entering the particulate medium.
