英文摘要	a pulse cleaner based on noncollinear optical-parametric amplification and second-harmonic generation processes is used to improve the contrast of a laser of peak intensity 2x10 ^19w/cm^2 to ~10^11 at 100 ps before the peak of the main pulse. a 7 mev proton beam is observed when a 2.5um-thick al foil is irradiated by this high-contrast laser. the maximum proton energy decreases to 2.9 mev when a low-contrast ( ~10 ^8) laser is used. two-dimensional particle-in-cell simulations combined with multi simulations show that the maximum proton energy sensitively relies on the detecting direction. the ns-time-scale prepulse can bend a thin target before the main pulse arrives, which reduces maximum proton energy in the target normal sheath acceleration.
