Free Electron Lasers [PDF]

Annual Review of Nuclear and Particle Science, 1985
The free electron laser (FEL) uses a high quality relativistic beam of electrons passing through a periodic magnetic field to amplify a copropagating optical wave (1-4). In an oscillator configuration, the light is stored between the mirrors of an open optical resonator as shown in Figure 1.

Controlling water-window high-harmonic generation with sub-cycle synthesized waveforms [PDF]

EPJ Web of Conferences, 2022
We present the first results concerning synthesizer-driven high-harmonic generation that reach the water-window region. This approach holds the promise of offering greater spectral tunability in the generation of isolated attosecond pulses and at the ...

Segmented Terahertz device for ultrashort electron acceleration, compression, focusing and streaking [PDF]

EPJ Web of Conferences, 2019
We present a segmented THz based device (STEAM) capable of performing multiple high-field operations on the 6D-phase-space of ultrashort electron bunches.

Picosecond pulse-shaping for strong three-dimensional field-free alignment of generic asymmetric-top molecules

Nature Communications, 2022
Field-free 3D alignment of complex molecules is an important step toward the imaging of molecular dynamics. Here, the authors demonstrate pulse-shaping of long picosecond pulses for the 3D field-free alignment of the prototypical non-rotation-symmetric ...

Superconducting undulator activities at the European X-ray Free-Electron Laser Facility

Frontiers in Physics, 2023
For more than 5 years, superconducting undulators (SCUs) have been successfully delivering X-rays in storage rings. The European X-Ray Free-Electron Laser Facility (XFEL) plans to demonstrate the operation of SCUs in X-ray free-electron lasers (FELs ...

Strong-field coherent control of isolated attosecond pulse generation

Nature Communications, 2021
Attosecond pulse generation needs improvements both in terms of tunability and photon flux for next level attosecond experiments. Here the authors show how to control the HHG emission and its spectral-temporal characteristics by driving the IAP ...

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.

Seeded Free-Electron Lasers and Free-Electron Laser Applications [PDF]

Synchrotron Radiation News, 2016
Several decades after the groundbreaking discovery of X-rays in 1895 by Wilhelm Conrad Roentgen, it became quite evident that the possibility of building X-ray sources with controlled photon beam parameters was a revolutionary step to address some of the important challenges facing humanity.
