Abstract :
Energetic ions and ultrashort X-rays were generated by an intense ultrashort laser interacting with a copper target. Fast ions up to 3 MeV were observed with CR-39 nuclear track detector sheets when a 7 TW laser was used. Cu12+~Cu17+ ions with the energy from 50 keV to 220 keV were detected with a Thomson parabola detector in the case of the laser power of 2.5 TW. Time-resolved X-ray diffraction was carried out using ultrashort X-rays generated from the copper target irradiated by the intense laser pulses. A change of diffraction patterns was observed in the X-ray diffraction from a GaAs(111) crystal irradiated by the ultrashort laser pulses
