脉冲强度-持续时间猜想：来自自由电子激光的证据
The Pulse Intensity-Duration Conjecture: Evidence from Free-Electron Lasers
摘要：
最近，G。Mourou和T. Tajima（Science 331，41（2011））关于驱动器激光脉冲的强度和所产生的脉冲的持续时间，即需要较高的驱动器光束强度来达到较短的辐射脉冲，至今仍然是没有明确理论推理的推测。在这里，我们提供它的情况下，相对论性电子束作为激光的辐射介质（自由电子激光）的推广。这也加强了对该猜想的基本物理原理的理解。
英文摘要：
The recent remark by G. Mourou and T. Tajima (Science 331, 41 (2011)) on the intensity of the driver laser pulse and the duration of the created pulse that higher driver beam intensities are needed to reach shorter pulses of radiation remains a conjecture without clear theoretical reasoning so far. Here we offer its extension to the case of relativistic electron bunches as the laser's radiating medium (free-electron laser). This also bolsters the understanding of the underlying physical principle of the Conjecture.
