    Emission of carbon currents reaching values up to 2 A/cm2 at a distance of 1 m from the laser ion source driven by the subnanosecond Prague Asterix Laser System operated at a fundamental wavelength of 1315 nm is reported. Graphite targets were exposed to intensities up to 5 x 1016 W/cm2 varying both the laser energy and the position of the laser beam focus with respect to the target surface. The maximum energy gain of carbon ions was ~1 MeV/u. At high laser intensities the shape of time-of-flight spectra is also formed by plasma outbursts, whose growth correlates with the oscillatory self-focusing of the laser beam.
