自由电子激光短脉冲滑移效应分析

An Analysis of the Slippage Effect in the Short Pulse FEL

对低增益及高增益自由电子激光的短脉冲滑移(slippage)效应分别进行了分析。对电子与光脉冲初始均为矩形脉冲时的情况,得到了相应的小信号光场解析式。

The slippage effect of short--pulse FEL is analysed for low gain and high gain ca-se respectively.In the case that the initial electron pulse and optical pulse are bothsquare, the analytical expression of the small signal optical field is obtained.
