标题： Fel Oscillators with Tapered Undulators: Inclusion of Harmonic Generation and Pulse Propagation

摘要： 我们回顾使用锥形波荡器的FEL振荡器的理论。 我们考虑均匀锥形的情况，并引入一个参数，该参数表征锥形对增益和饱和强度的影响。 我们通过包括脉冲传播效应来分析锥形对FEL动力学的影响。 我们分析锥形作为建模光脉冲形状和控制高次谐波强度的工具的重要性。 显示英文摘要

摘要： We review the theory of FEL oscillators operating with tapered undulators. We consider the case of a uniform tapering and introduce a parameter which characterizes the effect of the tapering on the gain and on the saturation intensity. We analyze the effect of the tapering on the FEL dynamics by including the pulse propagation effects too. We analyze the importance of tapering as a tool to model the optical pulse shapes and to control the higher harmonic intensities.
