Energetic ions at moderate laser intensities using foam-based multi-layered targets

• The experimental feasibility of the laser-driven ion acceleration concept with multi-layered,foam-based targets has been investigated. Targets with the required features have beenproduced and characterized, exploiting the potential of the pulsed laser deposition technique.In the intensity range 1016–1017 Wcm−2, they allow us to obtain maximum proton energies2–3 times higher compared to bare solid targets, able to reach and surpass the MeV range withboth low and ultrahigh contrast pulses. The results of two-dimensional particle-in-cellsimulations, supporting the interpretation of the experimental results, and directions to exploitthe concept also at ultrahigh intensities, are presented.
