Harmonic lasing in x-ray free electron lasers

Physical Review Special Topics. Accelerators and Beams, 2012
Harmonic lasing in a free electron laser with a planar undulator (under the condition that the fundamental frequency is suppressed) might be a cheap and efficient way of extension of wavelength ranges of existing and planned x-ray free electron laser ...

High efficiency, multiterawatt x-ray free electron lasers

Physical Review Accelerators and Beams, 2016
In this paper we present undulator magnet tapering methods for obtaining high efficiency and multiterawatt peak powers in x-ray free electron lasers (XFELs), a key requirement for enabling 3D atomic resolution single molecule imaging and nonlinear x-ray ...

Structural enzymology using X-ray free electron lasers

Structural Dynamics, 2017
Mix-and-inject serial crystallography (MISC) is a technique designed to image enzyme catalyzed reactions in which small protein crystals are mixed with a substrate just prior to being probed by an X-ray pulse. This approach offers several advantages over

Fast modeling of regenerative amplifier free-electron lasers

Physical Review Research, 2023
High-gain free-electron lasers (FELs) are becoming important light sources at short wavelengths such as the EUV and x-ray regimes. A particularly promising concept is the regenerative amplifier FEL (RAFEL), which can greatly increase the brightness and ...

Broadband optical gain via interference in the free electron laser: principles and proposed realizations [PDF]

, 2001
We propose experimentally simplified schemes of an optically dispersive interface region between two coupled free electron lasers (FELs), aimed at achieving a much broader gain bandwidth than in a conventional FEL or a conventional optical klystron ...

Vacuum birefringence at x-ray free-electron lasers

New Journal of Physics, 2021
We study the perspectives of measuring the phenomenon of vacuum birefringence predicted by quantum electrodynamics using an x-ray free-electron laser (XFEL) alone.

Tunability of free-electron lasers [PDF]

, 1995
In a free-electron laser oscillator, a variation in the electron beam energy leads to a change in the resonant optical frequency. Simulations are used to study the optical response to an electron beam energy change.
