摘要
利用动力学理论对一种新型自由电子激光──离子波纹激光（ＩＲＬ）进行了研究，考虑电子束的纵向动量离散和空间电荷场效应，导出了ＩＲＬ不稳定性色散关系，求得了ＩＲＬ辐射波的增长率及电子束空间电荷波的线性阻尼率，并对其进行了讨论，得到了一些结论。
Ion-Ripple Laser (IRL), which is a new form of free-electron laser, is investigated using the kinetic theory. By considering the finite spread in beam longitudinal momentum and the effect of finite space-charge field of the electron beam,the dispersion relation of IRL instability is derived ,and the growth rate of IRL wave and the linear damping rate of the space-charge wave are also got. Detail discussion is carried out ,and some important results are obtained.
