The intense isotropic source of multicharged ions with energy above 300 keV was produced by femtosecond Ti:Sa laser pulses with intensity 410 W/cm absorbed in the supersonic jet of the mixed He and CO gases. The spatial resolution of the ionographic image not worse than 600 nm was provided. A difference in object thickness of 100 nm was resolved very well for Zr and polymer foils both.
