Paper Abstract

Phthalocyanine coated targets, as well as tungsten, aluminum, and carbon targets are studied. Nanosecond and picosecond neodymium lasers capable of moderate output powers are used to produce 1011 to 1013 W/cm2 of incident intensity on the targets. The laser plasma temperature and electron density are measured by recording intensities and spectral shapes of ion lines in a spectral region from 40 to 300 nm. More than ten lines including Al3+ at 76.8 nm, Al2+ at 56 nm, Al+ at 237 nm, C3+ at 253 nm, and C2+ at 297 nm are observed and analyzed. The measurement technique permits us to determine electron density and electron temperature dependencies on the distance form the target surface ranging from 0.5 to 5 mm, where Ne greater than or equal to 1017 cm-3. For example, for an aluminum plasma at a distance 1 mm from the target, Ne equals 5 (plus or minus 1) 1017 cm-3 and Te equals 14 eV, respectively. For a new class of molecular materials (metal-phthalocyanines) an increased XUV output is observed due to effective laser radiation coupling into molecular targets. Different types of coatings (including fullerenes) are currently under investigation.
