摘要
对电子束有一定初始能量分散或角度分散时的自由电子激光小信号增益用较简便的方法进行了分析计算,并给出了一个渐近公式,结果与用计算机模拟解自由电子激光微分方程组得到的结果一致。
Free electron laser gain in the small-signal regime with an initial electron
beam energy spread or angular spread are directly calculated in a simple way. an asymptotic formula is derived: the result agree with the computer simulation.
