Photoelectron spectroscopy of 3s3p doubly excited helium dressed with strong near-infrared laser fields
Mizuho Fushitani, Chien-Nan Liu, Yuki Ono +9
We report time-resolved photoelectron spectroscopy of the doubly excited states of helium dressed by an intense near-infrared (NIR) laser field. Using synchronized XUV free-…

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$^…
