Title: Generation of low-divergence megaelectronvolt ion beams from thin foil irradiated with an ultrahigh-contrast laser

Abstract

Megaelectronvolt (MeV) ion beams with low divergence (10 Degree-Sign ) are experimentally generated from a thin foil irradiated by an ultrahigh-contrast laser at a peak intensity of {approx}10{sup 18} W/cm{sup 2}. The high-contrast ({approx}10{sup 11}) laser is obtained with a pulse cleaner based on noncollinear optical-parametric amplification and second-harmonic generation processes. The effects of the foil density, foil thickness, as well as the density gradients at the front and back sides of the foil are investigated with two-dimensional particle-in-cell simulations. The beam parameters of maximum energy and divergence strongly depend on the density gradients at the back side of the foil.
