When investigating the nonlinear interaction of EM fields of different polarizations within a gas medium, however, elastic depolarizing collisions, which lead to the redistribution of resonant atoms over the Zeeman sublevels, play an important role and cannot be neglected.This book provides a consistent theory of elastic depolarizing collisions, then uses this theory to investigate several nonlinear phenomena in a gas medium: Photon echoes: After in-depth discussions on the theory and nonlinear electrodynamics of the photon echo in a gas medium, the authors propose new experiments that may provide additional spectroscopic information.Double-mode lasing: Along with the theory of double-mode lasing in standing wave gas lasers, the authors show that elastic depolarizing collisions determine the minimum intermode separation that still provides stable double-mode lasing.- W eak and strong EM wave interaction: The authors present results that demonstrate the considerable influence of elastic depolarizing collisions on the interactions of weak and strong EM waves passing through a gas medium
