Short Rayleigh length free electron lasers
Physical Review Special Topics. Accelerators and Beams, 2006 Conventional free electron laser (FEL) oscillators minimize the optical mode volume around the electron beam in the undulator by making the resonator Rayleigh length about one third to one half of the undulator length.

Optical guiding in a free electron laser [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1985 Abstract The coherent interaction between an optical wave and an electron beam in a free electron laser (FEL) is shown to be capable of optically guiding the light. The effect is analyzed using a two-dimensional approximation for the FEL equations, and using the properties of optical fibers.

Ultrashort ultraviolet free-electron lasers [PDF]
Journal of X-Ray Science and Technology, 1994 In this work we combine elements of chirped pulse amplification (CPA) techniques, now familiar in solid-state lasers, with an amplifier based upon a seeded free-electron laser (FEL). The resulting device would produce amplified pulses of unprecedented brevity at wavelengths shorter than can be currently obtained by any tunable laser system.

Laser assisted electron beam conditioning for free electron lasers
Physical Review Special Topics. Accelerators and Beams, 2005 A new method for electron beam conditioning in free electron lasers is proposed. It uses the electron beam interaction with a laser light in two wiggler magnets separated by a strong-focusing channel.

Analysis of Čerenkov free-electron lasers
Physical Review Special Topics. Accelerators and Beams, 2015 We present an analysis of a Čerenkov free-electron laser (FEL) driven by a flat electron beam. In this system, an electron beam traveling close to a dielectric slab placed at the top of an ideal conductor interacts with the copropagating electromagnetic ...

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 ...
