利用已获得的大信号自由电子激光增益公式,导出了激光平均增长率表达式,分析了自由电子激光中电子与辐射波相互作用的有效时间,讨论了其主要物理参量对相互作用有效时间的影响
The expression of the average laser growth rate is deduced by using the obtained large-signal free-electron laser gain formula, and the effective time of the interaction between the electron and the radiation wave in the free-electron laser is analyzed. The influence of the main physical parameters on the effective time of the interaction is discussed
