从单粒子模型理论出发,对考虑空间电荷的自由电子激光进行了分析,并提出了迭代计算方法,计算结果表明,自由电子激光中三波耦合的一次迭代解与已有结果一致,二次迭代解显示了空间电荷波有更复杂的结构.
Based on the theory of single-particle model, the free-electron laser considering space charge is analyzed and an iterative calculation method is proposed. The calculation results show that the first iteration solution of the three-wave coupling in the free-electron laser is consistent with the existing one, The space charge wave shows a more complicated structure.
