We examine the impact of the hot drifting electron on stimulated Raman backscattering, which is coupled to decay instability, in a magnetized plasma. Through parametric coupling, this produces a plasma wave that moves forward and an electromagnetic wave that shifts downward. The plasma wave produced by stimulated Raman scattering (SRS) in this process decays into an ion-acoustic wave and a secondary, longer-wavelength Langmuir wave traveling opposite to the ion-acoustic wave. This energy diversion and attenuation of the primary Langmuir wave by drifting electrons limit the amplitude of SRS. In the presence of drifting electrons, the SRS is suppressed significantly and the plasma wave is attenuated resonantly at a higher rate.
