High Dose-Rate Ionizing Radiation Source from Tight Focusing in Air of a mJ-class Femtosecond Laser
S. Vallières, J. Powell, T. Connell +7
Ultrashort electron beams with femtosecond to picosecond bunch durations offer unique opportunities to explore active research areas ranging from ultrafast structural dynamics to u…
GeV electrons due to a transition from laser wakefield acceleration to plasma wakefield acceleration
P. E. Masson-Laborde, M. Z. Mo, A. Ali +6
We show through experiments that a transition from laser wakefield acceleration (LWFA) regime to a plasma wakefield acceleration (PWFA) regime can drive electrons up to energies cl…
Quasi-monoenergetic electron beams production in a sharp density transition
S. Fourmaux, K. Ta Phuoc, P. Lassonde +5
Using a laser plasma accelerator, experiments with a 80 TW and 30 fs laser pulse demonstrated quasi-monoenergetic electron spectra with maximum energy over 0.4 GeV. This is achieve…
Single shot phase contrast imaging using laser-produced Betatron x-ray beams
S. Fourmaux, S. Corde, K. Ta Phuoc +8
Development of x-ray phase contrast imaging applications with a laboratory scale source have been limited by the long exposure time needed to obtain one image. We demonstrate, usin…
Demonstration of the synchrotron-type spectrum of laser-produced Betatron radiation
S. Fourmaux, S. Corde, K. Ta Phuoc +10
Betatron X-ray radiation in laser-plasma accelerators is produced when electrons are accelerated and wiggled in the laser-wakefield cavity. This femtosecond source, producing inten…
Softening of the insulating phase near Tc for the photo-induced insulator-to-metal phase transition in vanadium dioxide
D. J. Hilton, R. P. Prasankumar, S. Fourmaux +6
We use optical-pump terahertz-probe spectroscopy to investigate the near-threshold behavior of the photoinduced insulator-to-metal (IM) transition in vanadium dioxide thin films. U…
