摘要

在立方非线性近似条件下，我们分析了电子束产生泵浦电场的过程及其对参量超外差自由电子激光器（FEL）放大部分空间电荷波（SCW）放大的影响。我们发现，产生的泵浦电场振幅在外部泵浦电场振幅的 21...33% 以内。我们发现产生的泵浦电场与外部泵浦电场相位一致。这导致了 SCW 生长增量的增加；因此，SCW 放大部分的长度减少了 22%。我们发现，这种电场不会破坏多谐 SCW 的放大模式。因此，所研究的效应使我们有可能制造出纵向尺寸更小的 FEL 和具有复杂多谐频谱的强大电磁波。

INFLUENCE OF GENERATED PUMP ELECTRIC FIELD ON MULTIHARMONIC INTERACTION OF WAVES IN AMPLIFICATION SECTION OF SUPERHETERODYNE FEL

In the cubic nonlinear approximation, we analyze the processes of generating the electric pump field by an electron beam and its effect on the amplification of space charge waves (SCW) in the amplification section of a parametric superheterodyne free-electron laser (FEL). We found that the generated pump electric field amplitude is within 21…33% of the amplitude of the external pump electric field. We showed that the generated pump electric field is in phase with the external one. It leads to an increase in the growth increments of SCW; therefore, the length of the SCW amplification section is reduced by 22%. We found out that this field does not destroy the mode of amplification of multi-harmonic SCW. Thus, the studied effect makes it possible to create FELs with smaller longitudinal dimensions and powerful electromagnetic waves with a complex multi-harmonic spectrum.
