Abstract : This report presents the basic structure and workings of a rigorous and comprehensive formalism applicable to the study of gaseous mixtures interacting with an electromagnetic field. It presents new analyses and characterizations of the physical effects produced by increasing the density of pressure of the gas. A brief discussion on the overall versatility of the general approach relative to strategic areas such as Brillouin scattering and Rydberg-state interactions, the extension of its theoretical limits to include such important current thrusts as adverse-condition imaging in fog or mist, and a rigorous study of the dynamics of the free-electron laser are also presented.
