"Beam `a la carte": laser heater shaping for attosecond pulses in a multiplexed x-ray free-electron laser
Siqi Li, Zhen Zhang, Shawn Alverson +19
Electron beam shaping allows the control of the temporal properties of x-ray free-electron laser pulses from femtosecond to attosecond timescales. Here we demonstrate the use of a…
Experimental Demonstration of Attosecond Pump-Probe Spectroscopy with an X-ray Free-Electron Laser
Zhaoheng Guo, Taran Driver, Sandra Beauvarlet +47
Pump-probe experiments with sub-femtosecond resolution are the key to understanding electronic dynamics in quantum systems. Here we demonstrate the generation and control of sub-fe…
Wavelength scaling and multi-color operation of a plasma driven attosecond X-ray source via harmonic generation
Rafi Hessami, Jenny Morgan, River Robles +3
The generation of high power coherent soft X-ray pulses of sub-100 as duration and 10 nm wavelength using beams from a GeV energy plasma wakefield accelerator has been recently inv…
Fast modeling of regenerative amplifier free-electron lasers
River R. Robles, Aliaksei Halavanau, Gabriel Marcus +1
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 regenerat…
