自由电子激光(free electron lasers) 定义:自由电子激光是利用自由电子为工作媒质产生的强相干辐射,它的产生机理不同于原子内束缚电子的受激辐射。自由电子激光的概念是John M. J. Madey于1971年在他的博士论文中首次提出的。自由电子激光是激光家族的一个新成员。 由于它的工作介质是自由电子,因此称为自由电子激光。
什么是自由电子激光器(Free Electron Lasers)? 自由电子激光器简介 自由电子激光器(FEL)是一种发射相干电磁激光脉冲的光源,脉冲长度很短,波长范围从毫米到X射线,取决于电子能量。FEL是由约翰-麦迪于1971年在斯坦福大学发明的,此后,许多FEL设施被建造出来,用于各种应用,包括生物医学应用。FEL的照明介质包含在磁性结构中...
We present a novel, highly versatile, and self-referenced arrival time monitor for measuring the femtosecond time delay between a hard X-ray pulse from a free-electron laser and an optical laser pulse, measured directly on the same sample used for pump-probe experiments. Two chirped and ...
Free-electron lasers create coherent light by constantly accelerating a beam of electrons. Free-electron lasers are particularly useful because they can produce radiation with a short-wavelength, down to just a few tenths of a nanometre. Thus, it is hoped they will become an important tool for ...

The meaning of FREE-ELECTRON LASER is a laser that can be tuned over a wide range of frequencies and that produces electromagnetic radiation by the motion of electrons moving at relativistic velocities in a magnetic field.
X-ray free-electron lasers (XFELs) have rapidly developed into unique tools for probing diverse systems of interest to different scientific disciplines with angstrom–femtosecond resolution. Claudio Pellegrini provides an overview of the milestones in the development of XFELs and their unique capabilities...
Free-electron lasers (FELs) are classical lasers that can provide widely tunable, highly intense, ultrashort laser pulses in any part of the spectrum. We present here the basic principles and advantages of FELs, discuss the emergence of self-amplified spontaneous emission FELs as leading candidates...
Free-electron lasers generate high-brilliance coherent radiation at wavelengths spanning from the infrared to the X-ray domains. The recent development of short-wavelength seeded free-electron lasers now allows for unprecedented levels of control on longitudinal coherence, opening new scientific avenues su...
