RESUMO

The iodine laser PALS operated at the fundamental 1ω0 and third harmonic 3ω0 frequencies (wavelengths 1315 nm and 438 nm, respectively) was used for the generation of plasmas of various Z-number targets. The investigation were performed at energies up to 800 J and 250 J for 1ω0 and 3ω0, respectively, in the 400 ps pulses. In these conditions attention is paid to the application of the solid state nuclear track detectors of the PM-355 type for measurements of parameters of ions emitted from the laser produced plasmas. Detector samples were masked with different Al.-foil filters for making possible a rough estimation of ion energy. Track densities of the order of magnitude >107 tracks/cm2 were observed on the uncovered detectors and on detectors masked with 0.75 and 1.5 μm thick Al.-foils. It confirms that Ag-, and Ta-ions of energy in the MeV range were emitted from the targets irradiated with the laser pulses. The ion streams were estimated on the basis of the track densities for different experimental conditions. The results were compared with those obtained with the use of ion collectors.
