As electron kinetic energy and undulator parameters can be adapted as desired, free-electron lasers are tunable and can be built for a wider frequency range than any other type of laser, [3] currently ranging in wavelength from microwaves, through terahertz radiation and infrared, to the visible spectrum, ultraviolet, and X-ray.
The European X-Ray Free-Electron Laser Facility (European XFEL) is an X-ray research laser facility commissioned during 2017. The first laser pulses were produced in ...
Serial femtosecond crystallography (SFX) is a form of X-ray crystallography developed for use at X-ray free-electron lasers (XFELs). [1] [2] [3] Single pulses at free-electron lasers are bright enough to generate resolvable Bragg diffraction from sub-micron crystals. However, these pulses also destroy the crystals, meaning that a full data set ...
An X-ray laser can be created by several methods either in hot, dense plasmas or as a free-electron laser in an accelerator. This article describes the x-ray lasers in plasmas, only. This article describes the x-ray lasers in plasmas, only.
The SPring-8 Angstrom Compact free electron LAser, referred to as SACLA (pronounced さくら (Sa-Ku-Ra)), is an X-ray free-electron laser (XFEL) in Harima Science Garden City, Japan, embedded in the SPring-8 accelerator and synchrotron complex. [1] [2] When it first came into operation 2011, it was the second XFEL in the world and the first in ...
The sample is first prepared in an excited state by a laser pulse and then probed by an X-ray pulse. With the advent of XFELs, sources that can provide extremely brilliant (more than five orders of magnitude larger than synchrotron sources) and extremely short X-ray pulses, X-ray spectroscopies performed in a pump and probe fashion are nowadays ...
In 2000 to 2001, the test facility at DESY was the first free-electron laser in the world to produce light flashes in the vacuum ultraviolet and soft X-ray range. [37] Today, the FLASH facility produces ultrashort light pulses in the soft X-ray range for seven experimental stations. [38]
SwissFEL is the X-ray free-electron laser at the Paul Scherrer Institute (PSI), which was inaugurated in December 2016. [1] The SwissFEL design is optimised to generate X-ray pulses in the wavelength range of 1 Å to 70 Å. With an overall length of just under 740 metres, the system configuration is relatively compact.
