Analysis of stimulated scattering of a high-frequency incident pump wave from an unmagnetized relativistic electron beam is presented. The backscattered radiation frequency can be enhanced by the factor 4..gamma../sup 2//sub 0/ over the incident pump frequency, where ..gamma../sub 0/ is the relativistic factor of the electron beam. The linear growth rates associated with the wave-wave and wave-particle modes of scattering, in the high gain limit, are examined for a number of different pump amplitude regimes. Estimates for the scattering efficiency are presented for the wave-wave scattering process.
