Abstract

Summary form only given. We present recent progress in our efforts to model electron transport and ionization dynamics in thin solid targets that are irradiated by ultra-short intense laser pulses, i.e. with intensities I>10¹⁸ W/cm² and pulse durations below 1 ps. Using numerically advanced multi-dimensional particle-in-cell models that include field- and electron impact ionization, as well as binary collisions between charged particles, we study the energy transfer and partition between fast and thermal electrons; propagation of an electron beam-driven ionization front; ultra-fast isochoric heating and the generation of shock waves in solid targets
