Popis: The interaction of short intense laser pulses with solid targets allows record-breaking ion energies to be attained at the laboratory scale. It has already been shown, that significant increase of ion energy arises in laser pulse interaction with ultrathin foil. Recent improvements of the intensity contrast ratio of pulses and advances in the technology of producing ultrathin targets warrant laser pulse interaction with ultrathin foils to be of practical interest. The electrons of the foil are capable of being heated up to MeV energies and form extended halo near the ion core. This triggers plasma expansion into a vacuum that provides acceleration of ions. A strong laser field can even knock out all electrons from a thin target that causes Coulomb explosion.
