Stimulated Scattering and Self-Focusing Processes in Dense Plasmas
During the years 1964 to 1966, there was a considerable amount of activity devoted to the investigation of optical non-linearities in plasmas1–7. At this time, attention was mostly confined to effects associated with non-linear excitation of the electron plasma mode. The stimulated scattering frequency mixing processes which were found to occur are analogous to the Raman type non-linearities which occur in neutral fluids and gases. It was also recognized at this time that, while the frequency mixing processes had promise of being observable, the stimulated scattering from the plasma mode was too weak to be of experimental importance4.
