Abstract
A multiple-scattering laser propagation model is developed in the form of three simultaneous partial differential equations for the reduced field amplitude, the forward- and the backscattered irradiances. The scattering and diffusion coefficients are defined in terms of Mie functions, and reduction factors are derived to take into account detection at limited fields of view. Solutions for transmitted beam profiles and integrated backscatter are compared with measurements performed on laboratory-generated water droplet clouds at 0.63, 1.06 and 10.6 mu m. The agreement is very good for all conditions investigated, ranging from negligible to important multiple-scattering contributions.
