摘要
本文用单粒子理论分析了主频电磁波为常振幅常相移情况下电磁波泵自由电子激光(EM-FEL)的边带不稳定性,推出了色散方程,求出了边带的振荡频率与线性增长率,进行了详细的讨论,得出了一些重要的结论。
Single-particle analysis of the electromagnetic free-electron laser(EM-FEL) sideband instability for primary wave with constant phase is presented in the paper. The dispersion equation is derrived, the oscillation frequency and linear growth rate of sideband instability are given. Detailed discussion is carried out and some important conclusions are drawn.
