Název v původním jazyce

Laser-driven ablation through fast electrons in PALS experiment at the laser radiation intensity of 1?50 PW/cm2

Popis výsledku v původním jazyce

The paper is directed to the study of high-temperature plasma and ablation plasma formation as well as efficiency of the laser energy transfer to solid targets irradiated by laser pulses at conditions corresponding to the characteristics of the laser spike designed to generate the igniting shock wave in the shock ignition concept. The experiments have been performed at PALS. The iodine laser delivered 250 ps (FWHM) pulses with the energy in the range of 100?600 J at the 1. and 3. harmonic frequencies.The diagnostic data collected using three-frame interferometry, X-ray spectroscopy, and crater replica technique were interpreted by two-dimensional numerical and analytical modeling which included generation and transport of fast electrons. The dominant contribution of fast electron energy transfer into the ablation process and shock wave generation was found when using the 1. harmonic laser radiation, the focal spot radius of 40?100 ?m, and the laser energy of 300?600 J.
