The results of particle-in-cell simulations are reported which demonstrate that a short-wavelength (lambda<=0.5 mum) short-pulse laser driver can produce much more intense ion beams than the commonly used long-wavelength (lambdaapprox1 mum) ones. In particular, such a driver allows for efficient generation of ultrashort (<=100 fs), multi-MeV proton bunches of extremely high intensities (>10{sup 21} W/cm{sup 2}) and current densities (>10{sup 14} A/cm{sup 2}) even at moderate values of dimensionless laser amplitude a{sub 0}<=10.
