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...
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 ...
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...

X-ray free-electron lasers (XFELs) are unique tools that are making possible time-resolved measurements of structural and electronic dynamics at the quantum spatial and temporal scales. Jonathan Marangos discusses the transformative scientific potential of this capability but also stresses the importance...
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.
Free electron lasers are electron beam-based sources of coherent, high-power tunable radiation which can, in principle, be designed to operate at any wavelength ranging from mm waves to X-rays. In recent years, these devices have successfully been operated at THz and hard X-ray wavelengths ...
During the last decades, the advent of the short-wavelength Free Electron Lasers (FELs) in the range from extreme ultraviolet (XUV) to hard X-rays has opened a new research avenue for the investigations of ultrafast electronic and structural dynamics in any form of matter. FELs deliver coherent...
