Abstract

The results of experimental studies of high-intensity proton beam generation at the interaction of a 350 fs laser pulse of 1.06μm or 0.53μm wavelength and intensity up to 2 × 10¹⁹Wcm^-2 with a thin (0.6 -3μm) solid target are reported. It is shown that collimated MeV proton beams of intensity ~ 10¹⁸ Wcm^-2 and current density ~ 10¹²Acm^-2 at the source can be produced when the laser-target interaction conditions approach the skin-layer ponderomotive acceleration requirements and the laser intensity-wavelength product is above 10¹⁹Wcm^-2μm². The effect of laser intensity, the target structure and the laser wavelength on the proton beam intensity and the laser-protons energy conversion efficiency are demonstrated.
