Spontaneous and Induced Coherent Radiation Generated in Atomic Vapor

Abstract

Optical coherent techniques have been developed and applied in order to obtain relaxation and spectroscopic information in atomic vapors. Theoretical work was performed to understand collisional relaxation and the interaction of intense fields with matter. The utility of using incoherent light fields in generating coherent excitations was demonstrated and analyzed. Applications of the time delayed four wave mixing technique using broadband light for investigating relaxation in solids have begun. Keywords: Photon echo, Stimulated echo, Incoherent echo, Billiard ball model, Collisionally induced relaxation, Attosecond beats, Ultrafast modulation spectroscopy, Diffraction free beams, Time delay, Four wave mixing.
