摘要

提出了一种由高功率微波超辐射脉冲泵浦的紧凑康普顿太赫兹自由电子激光器的方案，该激光器在准光学腔中循环，并在每电子能量为几兆电子伏特的适度相对论反传播电子束上进行多次后向散射。由光注入器形成的周期性电子束序列和由线性感应加速器产生的微秒电子束都可以作为电子源。已经证明了产生具有亚千兆赫重复率的多兆瓦相干太赫兹脉冲序列的可能性。

Use of Superradiance Pulses to Pump Multi-Pass Terahertz Compton Free Electron Lasers

A scheme of a compact Compton terahertz free electron laser pumped by a high-power microwave superradiance pulse, which circulates in a quasi-optical cavity and undergoes multiple backscattering on a moderately relativistic counterpropagating electron beam with an energy of several MeV per electron has been proposed. Both periodic sequences of electron bunches formed by photoinjectors and microsecond electron beams from linear induction accelerators can be used as sources of electrons. The possibility of generating a sequence of multimegawatt coherent terahertz pulses with a sub-gigahertz repetition rate has been shown.
