Micrometric thin targets have been irradiated in vacuum in TNSA (Target Normal Sheath Acceleration) configuration at PALS Laboratory in Prague by using 1016 W/cm2 laser intensity, 1315 nm wavelength, 300 ps pulse duration and different laser beam energies and focal positions. Time of flight techniques, time resolved imaging and ion deflection spectrometry were used to characterize the laser-generated non-equilibrium plasma and the electric field driving ion acceleration developed at the rear side of the target. Special targets containing nanostructures, induce resonant absorption effects enhancing the electric acceleration field. The maximum kinetic energy measured for protons was above 5.0 MeV.
