Ion acceleration by an ultrashort laser pulse interacting with a near-critical-density gas jet
M. Ehret, C. Salgado-Lopez, V. Ospina-Bohorquez +28
We demonstrate laser-driven Helium ion acceleration with cut-off energies above 25 MeV and peaked ion number above /MeV for 22(2) MeV projectiles from near-critical density…
Enhanced laser-driven proton acceleration with gas-foil targets
Dan Levy, Xavier Davoine, Arnaud Debayle +2
We study numerically the mechanisms of proton acceleration in gas-foil targets driven by an ultraintense femtosecond laser pulse. The target consists of a near-critical-density hyd…
Extremely Dense Gamma-Ray Pulses in Electron Beam-Multifoil Collisions
Archana Sampath, Xavier Davoine, Sébastien Corde +26
Sources of high-energy photons have important applications in almost all areas of research. However, the photon flux and intensity of existing sources is strongly limited for photo…
Synchrotron radiation from ultrahigh-intensity laser-plasma interactions and competition with Bremsstrahlung in thin foil targets
Bertrand Martinez, Emmanuel d'Humières, Laurent Gremillet
By means of particle-in-cell numerical simulations, we investigate the emission of high-energy photons in laser-plasma interactions under ultrahigh-intensity conditions relevant to…
Terahertz emission from submicron solid targets irradiated by ultraintense femtosecond laser pulses
J. Déchard, X. Davoine, L. Gremillet +1
Using high-resolution, two-dimensional particle-in-cell simulations, we investigate numerically the mechanisms of terahertz (THz) emissions in submicron-thick carbon solid foils dr…
Collisional effects on the electrostatic shock dynamics in thin-foil targets driven by an ultraintense short pulse laser
Andréas Sundström, Laurent Gremillet, Evangelos Siminos +1
We numerically investigate the impact of Coulomb collisions on the ion dynamics in high-, solid density caesium hydride and copper targets, irradiated by high-intensity ($I\appr…
