自由电子激光器的稳定脉冲解

STATIONARY PULSE SOLUTIONS FOR A FREE ELECTRON LASER

本文用自由电子激光器经典理论的数值解法,给出一组稳定脉冲解。计算表明,这种解只能在特定条件下获得,只要满足这些条件,解的形状与初始脉冲形状无关,对于微小扰动是稳定的,并保持传播不变。

The stationary pulse solutions for a free electron laser are obtained by using the classical theory. Computation shows that the stationary solutions can only be found under certain particular conditions. The shapes of the solutions do not depend on the shapes of initial optical pulses as long as these conditions are satisfied.
