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.
