Nonlinear resonant X-ray Raman scattering
Johann Haber, Andreas Kaldun, Samuel W. Teitelbaum +12
We report the observation of a novel nonlinear effect in the hard x-ray range. Upon illuminating Fe and Cu metal foils with intense x-ray pulses tuned near their respective K edges…

Superfluorescence, free-induction decay, and four-wave mixing: propagation of free-electron laser pulses through a dense sample of helium ions
James R Harries, Hiroshi Iwayama, Susumu Kuma +9
We report an experimental and numerical study of the propagation of free-electron laser pulses (wavelength 24.3 nm) through helium gas. Ionisation and excitation populates the He$^…
