带轴向引导磁场自由电子激光的工作参数选择

Choice of the Parameters in a Free-electron Laser with an Axial-guide Magnetic Field

利用电子能量守恒定律、轨道稳定性条件和静电模稳定性条件,给出了能使轴向引导磁场对增益起放大作用的自由电子激光器件的参数取值范围。

The regimes, in which the guide-field enhance the gain, are obtained for a freeelectron laser by using the conservation of electron energy, orbital stability condition, and electrostatic stability condition.
