Název v původním jazyce

Ablation instability experimentally observed on the thin foil metal target surface during its irradiation by terawatt laser

Popis výsledku v původním jazyce

Time evolution of plasma density modulations in case of thin foil metal targets was observed during the irradiation with focused terawatt iodine PALS laser beam. These modulations were simultaneously recorded using femtosecond interferometry in three time frames and x-ray streak camera allowing to determine growth and decay rates of hydrodynamic instabilities. These modulations were observed during the laser-plasma interaction, in particular several hundred picoseconds before its maximum intensity. Hot electron emission characteristics were measured and analyzed using an angular array of electron spectrometers. Weaker emission of hot electrons from the lead plasma was observed in comparison to lower Z materials.
