TL;DR: Discovery of a laser–plasma acceleration mechanism that generates 20 MeV proton beams with a 1% spread is a promising step in the development of laser-driven proton accelerators.

TL;DR: In this paper, the Weibel instability, a possible mechanism for developing such shocks, has been generated in a laboratory set-up with laser-generated plasmas, and it has been shown that collisionless plasma shock waves are often driven by collisionless shock waves.

TL;DR: Three-dimensional particle in cell simulations show that the intensity within the guided filament is amplified beyond its initial focused value to a normalized vector potential of a0>6, thus driving a highly nonlinear plasma wave.

TL;DR: It is shown that monoenergetic ion beams can be accelerated by moderate Mach number collisionless, electrostatic shocks propagating in a long scale-length exponentially decaying plasma profile and that it is possible to generate ~200 MeV proton beams with state-of-the-art 100 TW class laser systems.

TL;DR: Raman amplification has been proposed as a means to generate high-power laser pulses without the bulky and expensive components of conventional lasers, but with limited success as mentioned in this paper, and large-scale three-dimensional simulations enable researchers to identify conditions under which these limitations might be overcome.
