微型自由电子激光电子运动特性分析

作者曾首次提出以铁电单晶表面势代替摇摆器磁场的自由电子激光新机制.本文从单电子的洛仑兹方程出发,对电子的单摆方程,共振行为进行了研究,获得了第j个表面势共振态的增益公式.单摆方程和文献[1]中从能量方程得到的一致,本文的研究充实了文献[1]的论据。

ANALYSIS OF MOTION BEHAVIOTS OF ELECTRONS IN A MINIATURE FEL

A new mechanism for free electron lasers, in which the surface potential of a ferroelectric single crystal may be in place of the wiggler magnetic field, was proposed by the author for the first time [1]. Further studies have been made in this article. According to one-body z-coordinate equation of Lorentz equation, the research about simple pendulum equations and resonant behavior of electrons is carried out. The gain formula of the miniature free electron laser for the jth state of surface potential is given as follows:The simple pendulum equations are the same as given in literature [1] .The argument in literature [ 1] is substantiated.
