TL;DR: In this paper, the authors investigated the acceleration of ions from ultrathin foils irradiated by intense circularly polarized laser pulses using one-and two-dimensional particle simulations and provided insights on how to control the energy, number, and energy spread of accelerated ions.

TL;DR: Nanostructured thin plastic foils have been used to enhance the mechanism of laser-driven proton beam acceleration, leading to a consequent increase in the maximum proton energy and beam charge and to the first experimental demonstration of such advanced target geometry.

TL;DR: The interaction of laser pulses with thin grating targets, having a periodic groove at the irradiated surface, is experimentally investigated and an enhanced laser-target coupling is demonstrated for the first time in the relativistic regime of ultrahigh intensity >10(19) W/cm(2).

TL;DR: In this paper, the authors present theoretical analysis and experimental results concerning the major physical issues in the shock-ignition approach, which are the following: generation of a high amplitude shock in the imploding target, laser-plasma interaction physics under the conditions of high laser intensities needed for high-amplitude shock excitation, symmetry and stability of the shock propagation, role of fast electrons in the symmetrization of shock pressure and the fuel preheat.

TL;DR: In this paper, a monolayer of polystyrene microspheres of a size similar to the laser wavelength on the front surface of a thin foil was used for ion acceleration experiments.
