近年来，人们对短电子束相干辐射的研究越来越感兴趣。利用中小型射频（RF）加速器在远红外和毫米波区域实现紧凑的自由电子器件的可能性刺激了许多理论和实验研究，以澄清这一过程中的基本物理问题。本文将对相干发射实验进行综述。测量了单束相干发射的时间和光谱特性以及连续束之间的相干性，并分析了相干性对激光动力学的影响。
In the last few years there has been a growing interest in the study of coherent radiation from short electron bunches. The possibility of realizing compact FEL devices in the far-infrared and millimeter wave regions utilizing small to medium size radio-frequency (RF) accelerators has stimulated a number of theoretical and experimental investigations to clarify basic physics issues in this process.Coherent emission experiments will be reviewed in this paper. Measurements on the temporal and spectral characteristics of the coherent emission from a single bunch and on the coherence between consecutive bunches will be presented along with an analysis of the influence of coherence on the dynamics of the laser.
