“…A major laser upgrade is presently under preparation, comprising an increase in pulse energy to 500 mJ (pre-compression, about twice the present value). Following the dotted trend line of Figure 8 we assume that this should give rise to protons of 3 MeV maximum energy at least; former experiments even achieved 4-5 MeV [15,20,21]. At the same time the total number of protons (of the order 10 6 -10 7 /msr) may increase to 10 7 -10 8 /msr as suggested by previous publications under similar conditions [8,9,13,18,21,30].…”

A: We report on benchmark tests of a 3 TW/50 fs, table-top laser system specifically developed for proton acceleration with an intrinsic pump rate up to 100 Hz. In two series of single-shot measurements differing in pulse energy and contrast the successful operation of the diode pumped laser is demonstrated. Protons have been accelerated up to 1.6 MeV in interactions of laser pulses focused on aluminium and mylar foils between 0.8 and 25 µm thickness. Their spectral distributions and maximum energies are consistent with former experiments under similar conditions. These results show the suitability of our system and provide a reference for studies of laser targets at high repetition rate and possible applications.

“…Indications of dominant front side acceleration due to resistivity effects have been reported in solid plastic targets (Lee et al, 2011 and also in low-density foams (Li et al, 2005) where an anomalously high resistivity might be due to spatially localized fields in the locally inhomogenous material.…”

Ion acceleration driven by superintense laser pulses is attracting an impressive and steadily increasing\ud effort. Motivations can be found in the applicative potential and in the perspective to investigate novel regimes as available laser intensitieswill be increasing. Experiments have demonstrated, over a wide range\ud of laser and target parameters, the generation of multi-MeV proton and ion beams with unique properties\ud suchas ultrashort duration, high brilliance, and low emittance. An overview is given of the state of the art of\ud ion acceleration by laser pulses aswell as an outlook on its future development and perspectives.The main\ud features observed in the experiments, the observed scaling with laser and plasma parameters, and the main\ud models used both to interpret experimental data and to suggest new research directions are described

“…When a relativistically intense laser pulse irradiates a thin foil, the laser energy may be efficiently converted to a well-collimated beam of accelerated ions [20,24,25,32,33,67,74,75,78,84,91,95,124,133,158,170,193,244,246,250].…”
