Abstract

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× 10 ¹⁶ 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.
