| 摘 要： | 本文从单粒子模型出发,导出了考虑相对论能量因子一级扰动量影响的色散方程。结果表明:当入射电子能量足够大时,自由电子激光放大器出现频谱振荡现象,产生这种现象的原因是由于相对论能量因子的扰动作用。文中对此进行了比较详细的讨论。

| Abstract: | In this paper, on the basis of a single-particle model, the dispersion equation is obtained after considering the first perturbation term of relativistic energy factor. The results show that the frequency spectrum of free electron laser amplifier (FELA) exhibit oscillating phenomenon when injected electron energy is large enough. The origin of this phenomenon is attributed to perturbing effect of the relativistic energy factor. A some what detailed discussion is given. |
