我们报告的生产高功率（20 W的平均值，约1兆瓦的峰值）宽带太赫兹光的基础上相干发射的相对论电子。我们描述了源，提出理论计算和实验验证。为了清楚起见，我们比较这个源与基于超快激光技术的源，并且事实上辐射具有与由这样的源产生的辐射非常类似的品质，即它是空间相干的，并且包括具有变换限制光谱内容的短持续时间脉冲。然而，与传统的太赫兹辐射相比，由于相对论增强，强度大了许多数量级。
We report the production of high power (20 W average, approximately 1 MW peak) broadband THz light based on coherent emission from relativistic electrons. We describe the source, presenting theoretical calculations and their experimental verification. For clarity we compare this source with that based on ultrafast laser techniques, and in fact the radiation has qualities closely analogous to those produced by such sources, namely that it is spatially coherent, and comprises short duration pulses with transform-limited spectral content. In contrast to conventional THz radiation, however, the intensity is many orders of magnitude greater due to the relativistic enhancement.
