| Popis: | Stimulated coherent scattering of an electromagnetic wave by a relativistic electron beam is investigated in the framework of the three-wave approximation for the case of noncollinear geometry, when both the incident and scattered waves can propagate at an arbitrary angle to the beam direction. A dispersion equation is derived with which the collective and single-particle scattering regimes can be considered from the same viewpoint and the influence of an external electromagnetic field on electron motion in the field of the combined waves can be taken into account. Equations are obtained for the growth rates that provide a simple description of the applicability regions of various stimulated-scattering regimes and can be used for estimates for an optimal free-electron laser with noncollinear scattering geometry. |
