摘要：

Basic properlies of high-cuffent high-intensity ion beam generation using laserinduced skin-layer ponderomotive acceleration (SLPA) are discussed. The results of a recent experiment in which 0.35-ps laser pulse of intensity up to 2 x 10(19)W/cm(2) irradiated a thin (1-3 mu m) PS (plastic) or Au/PS target (PS covered by 0.1-0.2 mu m An front layer), are presented. It is shown that multi-MA proton beams of current densities > 1TA/cm(2) and intensities > 10(18) W/cm(2) at the source can be produced when the laser-target interaction conditions approach the SLPA requirements. The proton beam parameters as well as the laser-protons energy conversion efficiency substantially depend on the target structure and can be significantly increased with the use of a double-layer Au/PS target. A prospect for the application of SLPA-driven proton beams in ICF fast ignition research is outlined.
