摘要：

Laser driven proton acceleration experiments from micron and submicron thick targets using high intensity (2 x 10(21) W/cm(2)), high contrast (10(-15)) laser pulses show an enhancement of maximum energy when hydrogen containing targets were used instead of non-hydrogen containing. In our experiments, using thin (<1 mu m) plastic foil targets resulted in maximum proton energies that were consistently 20%-100% higher than when equivalent thickness inorganic targets, including Si3N4 and Al, were used. Proton energies up to 20MeV were measured with a flux of 10(7) protons/MeV/sr. (C) 2013 AIP Publishing LLC.
