The results of particle-in-cell simulations are reported which demonstrate that a short-wavelength (λ≤0.5 μm) short-pulse laser driver can produce much more intense ion beams than the commonly used long-wavelength (λ∼1 μm) ones. In particular, such a driver allows for efficient generation of ultrashort (≤100 fs), multi-MeV proton bunches of extremely high intensities (>1021 W/cm2) and current densities (>1014 A/cm2) even at moderate values of dimensionless laser amplitude a0≤10.
