The physics of laser-plasma interaction is studied on the Shenguang III prototype laser facility under conditions relevant to inertial confinement fusion designs. A sub-millimeter-size underdense hot plasma is created by ionization of a low-density p

Reliable simulations of laser–target interaction on the macroscopic scale are burdened by the fact that the energy transport is very often non-local. This means that the mean-free-path of the transported species is larger than the local gradient sc

Comprehensive understanding and possible control of parametric instabilities in the context of inertial confinement fusion (ICF) remains a challenging task. The details of the absorption processes and the detrimental effects of hot electrons on the i

The choice of the correct density profile is crucial in laser wakefield acceleration. In this work, both subsonic and supersonic gas targets are characterized by means of fluid-dynamic simulations and experimental interferometric measurements. The

A high-energy, high-yield proton beam with a good homogeneous profile has been generated from a nanosphere target irradiated by a short (30-fs), intense (7×10^{20} W/cm^{2}) laser pulse. A maximum proton energy of 30 MeV has been observed with a hig

Acceleration of ions from ultrathin foils irradiated by intense circularly polarized laser pulses is investigated using one- and two-dimensional particle simulations. A circularly polarized laser wave heats the electrons much less efficiently than th

A sub-grid foam model is developed to describe numerically a sequence of processes transforming solid elements in the foam into a hot plasma under the energy deposition by lasers. We account for three distinct processes: accurate laser energy absorpt

In this work we focus on the reconstruction of the density profiles from tomographic measurements. We compare different analytical and iterative methods, and we propose a new one tailored for the reconstruction of gas targets.
