Abstract

The current study illustrates the occurrence of Stimulated Raman Scattering (SRS) within a plasma channel characterized by magnetized density conditions. Stimulated forward Raman scattering takes place when a laser beam with a q-Gaussian profile traverses a plasma while being exposed to a wiggler magnetic field. The coupling between the applied magnetic field and the generated Langmuir wave ensures the Raman process generation. As a result, second Langmuir wave is produced which remains strongly damped on the electrons. An external magnetic field is employed for the effective suppression of the SRS. The initial enhancement in the growth rate is observed with the magnetic field and after attaining the maxima, it suppresses with the growth rate.
