Abstract:

This document reports on a theoretical and experimental study of the influence of collisions on the saturation spectroscopy line shapes associated with three-level gas vapor systems. The study is carried out with the goal of gaining new information concerning a the collisional processes that occur in atomic vapors, b the nature of the interatomic potential between a ground state and an excited-state atom and c the possibility of collision-induced enhancement of the absorption of radiation by an atomic system. In each of these areas, new results are obtained.
