Monoenergetic ion acceleration using the radiation pressure of high intensity lasers has attracted a strong interest in recent years and holds promise for numerous applications. Laser particle simulations have shown that radiation pressure acceleration (RPA) is the dominant acceleration mechanism leading up to GeV proton energies for peak intensities of the order of 1023 W/cm2. Using a peak intensity of 5 · 1019 W/cm2, however, we have observed the onset of RPA at the "JETI" laser system. This has been achieved using multi-component foil targets matching the density and thickness conditions for efficient RPA.
