Laser-pumped x-ray free electron laser

2008 IEEE 35th International Conference on Plasma Science, 2008
Ultrashort, high-brightness X-ray pulses are an important tool in many areas of research. In principle, a laser-pumped free-electron laser (FEL) can generate coherent, polarized X-ray for this purpose. In a laser-pumped X-ray FEL an intense laser field replaces the magnetic wiggler field of a conventional FEL.

Gas, Chemical, Free Electron, and X-Ray Lasers

1998
In this chapter, the most important types of lasers involving low density active media are considered, namely gas, chemical and free electron lasers. Some considerations on X-ray lasers involving highly ionized plasmas will also be presented. The main emphasis, again, is to stress the physical behavior of the laser and to relate this behavior to the ...

VUV and X-ray free-electron lasers

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2001
Abstract Recent advances in linear accelerators, new developments in laser driven low-emittance electron guns, and the feasibility of ultra-precise long undulators open up the exciting possibility of building single pass Free-Electron Lasers (FELs) based on self-amplified spontaneous emission (SASE).

Next-Generation X-Ray Free-Electron Lasers

IEEE Journal of Selected Topics in Quantum Electronics, 2012
Research frontiers for future free-electron lasers are discussed. Attention is given to ideas for improving the temporal coherence and obtaining subfemtosecond X-ray pulses. Improving brightness of the electron bunches is considered to be a major step forward for an electron beam accelerator simultaneously supporting multiple free-electron laser lines.

X-Ray Spectroscopy at Free Electron Lasers

2016
This chapter describes how spectroscopic measurements differ when moving to x-ray free electron lasers (XFELs) and presents some examples of how these novel x-ray sources have been applied to date. It focuses on the primary differences between storage ring sources and XFELs for time-resolved measurements.
