Interaction of high-power laser pulses with low-density targets in experiments with the PALS installation

Article

Abstract

Numerical modeling of experiments on the interaction of high-power pulses with low-density porous media is considered. The experimental data were obtained by means of the PALS iodine laser (pulse energy up to 200 J and pulse duration of 0.4 ns). The original density of the porous medium varied from 2.25 to 18 µg/cm3. A new physico-mathematical model of such plasma is proposed, two-dimensional computations are performed, and good agreement between the calculated and experimental data is shown
