摘要：

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 4γ2 0 over the incident pump frequency, where γ0 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.
