Abstract

A quantitative theory was developed for suppression of the premature pump side scattering by noise in backward Raman amplification (BRA). The pump frequency chirp was found to suppress parasitic pump side scattering in all directions approximately to the same extent as in the longitudinal direction. The pondermotive potential was found to be proportional to the scalar product of the electromagnetic wave polarizations. The results show that the two detuning mechanisms that are pump frequency chirp along with an appropriate plasma frequency gradient can suppress parasitic pump scattering.
