TL;DR: In this paper, the acceleration of multi-MeV protons from the rear surface of thin solid foils irradiated by an intense ($\ensuremath{\sim}{10}^{18}\text{ }\text{ W}/{\mathrm{cm}}^{2}$) and short (1.5

TL;DR: This concept paves the way for the generation of sub-μm-size, ultralow-emittance, highly tunable electron bunches, thus enabling a flexible new class of an advanced free electron laser capable high-field accelerator.

TL;DR: The propagation in a rarefied plasma of collisionless shock waves and ion-acoustic solitons, excited following the interaction of a long and intense laser pulse with solid targets, has been investigated via proton probing techniques.

TL;DR: Observations reveal that the absolute efficiency of the harmonics declines for the steepest plasma density scale length L(p)→0, thus demonstrating that near-steplike density gradients can be achieved for interactions using high-contrast high-intensity laser pulses.

TL;DR: The transport of an intense electron-beam produced by the Vulcan petawatt laser through dense plasmas has been studied by imaging with high resolution the optical emission due to electron transit through the rear side of coated foam targets and it is observed that the MeV-electron beam undergoes strong filamentation and the filaments organize themselves in a ringlike structure.
