| 摘 要： | Madey定理是关于自发辐射与受激辐射之间关系的一个定理,它是自由电子激光中的一个基本定理。本文对渡越辐射自由电子激光器研究了这个问题,结果表明,Madey定理的第一部分在渡越辐射自由电子激光中也存在对应的形式,但远为复杂;定理的第二部分形式不变。最后用所得结果进行了小信号增益的简化计算。

| Abstract: | As a fundamental theorem in free electron lasers, Madey Theorem reveals the relationship between the spontaneous radiation and the stimulated radiation. In this paper, this problem is studied for transition radiation free electron lasers. The results show that there is a formula corresponding to the first part of Madey Theorem, but the former is more complicated; while the second part remains the same. Then the results obtained are used to simplify the small signal gain calculation. |
