Paper Abstract

The advantages of a high-power KrF laser system 'GARPUN' generating UV radiation of 248 nm wavelength, 100 J energy and 100 ns pulse duration for the production of megabar range ablation pressures are demonstrated. The scaling law for the pressure dependence on laser intensity reaching 5*1012 W/cm2 was established and compared with other wavelengths. High-pressure material investigations were carried out with the emphasis on a shock wave dynamics and equation of state studies. Pressure-induced transformation of the pyrolytic graphite into a diamond-like phase was observed for the first time in laser-target interactions.
