TLDR
An intense proton beam to achieve fast ignition is proposed, produced by direct laser acceleration and focused onto the pellet from the rear side of an irradiated target and can be integrated into a hohlraum for indirect drive ICF.Abstract:
The concept of fast ignition with inertial confinement fusion (ICF) is a way to reduce the energy required for ignition and burn and to maximize the gain produced by a single implosion. Based on recent experimental findings at the PETAWATT laser at Lawrence Livermore National Laboratory, an intense proton beam to achieve fast ignition is proposed. It is produced by direct laser acceleration and focused onto the pellet from the rear side of an irradiated target and can be integrated into a hohlraum for indirect drive ICF.read more

Optics in the relativistic regime
TL;DR: In this paper, a number of consequences of relativistic-strength optical fields are surveyed, including wakefield generation, a relativistically version of optical rectification, in which longitudinal field effects could be as large as the transverse ones.

Ion acceleration by superintense laser-plasma interaction
TL;DR: An overview of the state of the art of ion acceleration by laser pulses as well as an outlook on its future development and perspectives are given in this article. But the main features observed in the experiments, the observed scaling with laser and plasma parameters, and the main models used both to interpret experimental data and to suggest new research directions are described.

Review of laser-driven ion sources and their applications.
TL;DR: The historical background including the early laser-matter interaction studies on energetic ion acceleration relevant to inertial confinement fusion is reviewed and several implemented and proposed mechanisms of proton and/or ion acceleration driven by ultra-short high-intensity lasers are described.
