Faraday rotation versus stimulated Raman scattering in intense sources

Abstract

A coherent plasma process such as the stimulated Raman scattering plays significant role in bringing about the changes in polarization characteristics of radiation. It is found that some of the observed polarization properties such as rapid temporal variations, sense reversal, rotation of the plane of polarization and change of nature of polarization in the case of pulsars and quasars, could be accounted for through stimulated Raman scattering
