摘要
介绍了史密斯──帕塞尔效应慢波自由电子激光（S－PFEL）用三镜准光学谐振腔系统；利用光学谐振腔衍射理论，采用面对称近似又坐标旋转的方法建立模型，对胜场特性进行分析，给出工作方程，完成数值模拟，并在毫米波段进行冷测实验。分析及实验结果表明，给出的方法可用来有效、快捷的分析和设计面对称三镜准光学谐振腔系统。设计的模型已成功用于S－PFEL实验。
S-P FEL quasi-optical open resonator system with three-mirror are introduced in this paper. By means of the diffracted theory of quasi-optical resonator, this paper analyzes and calculates the characteristics of the system by the principle of mirror symmetry and the method of rotating coordinate system. The corresponding model charts and testing results on 3 mm band are given. The numerical simulation and experimental results show that the method is effective.
