“…As a result, some transient and/or low-cross-section nuclear reactions, hardly observable with conventional accelerators, could be feasible to be studied. Using sub-GeV and GeV protons (I L 10 22 -10 24 W/cm 2 ), efficient production of pions and muons as well as neutrino beams is possible [77]. Yet higher energies of laser produced ions (~100 GeV for protons or 1 GeV/nucleon for heavy ions) could potentially open up the opportunity to conduct new fundamental physical research that would range from studies of the strong force to the production of quark-gluon plasmas.…”

The great progress in high-peak-power laser technology has resulted recently in the production of ps and subps laser pulses of PW powers and relativistic intensities (up to 1021 W/cm2) and has laid the basis for the construction of multi-PW lasers generating ultrarelativistic laser intensities (above 1023 W/cm2). The laser pulses of such extreme parameters make it possible to produce highly collimated beams of electrons or ions of MeV to GeV energies, of short time durations (down to subps) and of enormous currents and current densities, unattainable with conventional accelerators. Such particle beams have a potential to be applied in numerous fields of scientific research as well as in medicine and technology development. This paper is focused on laser-driven generation of fast ion beams and reviews recent progress in this field. The basic concepts and achievements in the generation of intense beams of protons, light ions, and multiply charged heavy ions are presented. Prospects for applications of laser-driven ion beams are briefly discussed.

“…Fig.1 points toward the existence of a window for full exploitation of the original pump power. More precisely, a faint, chirped, wideband seed signal could be amplified by a chain of Type I amplifiers [27] and finally enter the power KDP-based amplifier depleting the intense pump wave 6 . However, a significant improvement in bandwidth can be achieved operating the system in non-collinear mode.…”

“…It has long been understood that fast ion generation is related to the presence of hot electrons [5]. A variety of effects occur when the main source of acceleration is charge displacement due to the electron motion in the plasma or inductive electric fields from self generated magnetic fields [6]. However, for higher laser intensities (10 23 W/cm 2 ) acceleration results from the laser pressure exerted to the comoving electron-ion system; the latter acts as a progressively more opaque screen for the laser light and, in this case, charge displacement only plays the role of rectifier for the transversal laser field and as a medium for electron-ion energy transfer during light absorption.…”

The existence of efficient ion acceleration regimes in collective laser-plasma interactions opens up the possibility to develop high-energy physics facilities in conjunction with projects for inertial confinement nuclear fusion (ICF) and neutron spallation sources. In this paper, we show that the pulse compression requests to make operative these acceleration mechanisms do not fall in contradiction with current technologies for high repetition rate ICF drivers. In particular, we discuss explicitly a solution that exploits optical parametric chirped pulse amplification and the intrinsic modularity of the lasers aimed at ICF.

“…We have in mind that the power density about 1*10 18 W/cm 2 is enough to produce some types of nuclear reaction without special field concentrators. Estimation of the maximal energy of the proton inside the electromagnetic wave with wavelength λ and intensity I can be done by [9]:…”
