We discuss the concept of creating sources operated in the sub-terahertz/terahertz frequency range with a multi-megawatt power level and based on the coherent spontaneous emission of intense electron bunches. The possibility of forming such bunches is due to the development of modern photo injection systems. The results of theoretical analysis and computer simulation of the dynamics of electron bunches are reported and estimates of the parameters of high-power pulse sources in these ranges based on undulatory and cyclotron radiation mechanisms are presented.

基于由光注入器形成的电子束的相干自发发射的强大太赫兹辐射源

我们讨论基于强电子束的自发自发发射，以兆兆赫兹/太赫兹频率范围工作，具有几兆瓦功率水平的源的概念。形成这种束的可能性是由于现代照片注入系统的发展。报告了电子束动力学的理论分析和计算机仿真结果，并基于波动和回旋加速器的辐射机理，估算了这些范围内的高功率脉冲源的参数。
