The scattering of electromagnetic radiation by clouds of various particles has been a topic of continuing scientific interest. The advent of the laser has allowed these studies to be pursued into the visible portions of the spectrum. The report is concerned with The attenuation of a laser beam by flowing particulate clouds of various materials The empirical determination of the extinction coefficient of graphitic carbon under high power laser beam interaction with a flowing particulate cloud of graphitic carbon The determination of the index of refraction of graphitic carbon and The use of this index to determine the theoretical extinction coefficient of the graphitic carbon on a single particle basis.
