Monte Carlo simulation of the energy distribution in laser-irradiated solids under the influence of a magnetic field — •Xavier del Arco, Julia Amann, Pavel N. Terekhin, and Baerbel Rethfeld — Department of Physics and Research Center OPTIMAS, Technische Universität Kaiserslautern, Erwin-Schrödinger-Strasse 46, 67663 Kaiserslautern, Germany

The complex phenomenon arising after irradiation of a solid with ultra-short laser pulse is studied using a Monte Carlo simulation. Two possible electron interactions are considered: inelastic scattering and impact ionization. The influence of the external homogeneous magnetic field on the energy exchange between the electron and lattice subsystems is investigated. The results of this simulation contain the information about the evolution of the electron density, electron and lattice energy distributions. The developed approach can be used to study the influence of the magnetic field on the energy deposition and develop optimal strategies to improve ablation processes in solids.
