在电子振荡器的反馈回路中加入非线性可饱和吸收体，可以产生周期性的强超短微波脉冲序列。这种脉冲形成方法类似于激光物理学中广泛使用的被动锁模。然而，当由于波群速度和电子轴向速度之间的差异引起的束上的脉冲滑动而从静止电子束的不同部分中连续提取能量时，脉冲放大机制中存在一个特定特征。结果，所产生的“巨大”脉冲的峰值功率不仅可以超过稳态产生的水平，而且在最佳情况下，还可以超过驱动电子束的功率。
A periodic train of powerful ultrashort microwave pulses can be generated in electron oscillators with a non-linear saturable absorber installed in the feedback loop. This method of pulse formation resembles the passive mode-locking widely used in laser physics. Nevertheless, there is a specific feature in the mechanism of pulse amplification when consecutive energy extraction from different fractions of a stationary electron beam takes place due to pulse slippage over the beam caused by the difference between the wave group velocity and the electron axial velocity. As a result, the peak power of generated “gigantic” pulses can exceed not only the level of steady-state generation but also, in the optimal case, the power of the driving electron beam.
