Paper Abstract

Pulse broadening due to multiple scattering has long been of fundamental importance in the study of laser pulse transmission through the ocean as well as other diverse areas of science such as astrophysics, meteorology, and medical physics. We have used a Monte Carlo simulation to investigate the spatial and temporal spreading of a pulse (`pulse stretching') as it propagates through a medium due to small angle multiple scattering as described by van de Hulst and Kattawar. We show the transformation of single scatter distributions into those predicted by the central limit theorem. We also derive the scattering property of the medium finding a simple relation between the phase function and the scattering parameter which connects the single scatter mean square scattering angle, <(Theta) 2>, and the multiple scatter expectation value, <(Theta) 2>, along with well defined limits of validity of the present theory in terms of the basic scattering parameters of the medium.
