Modeling of irradiation by short laser pulse — Comparison of Boltzmann transport equation and a two-temperature model with experimental data

Abstract

: The presented paper investigates two methods of heat transfer problem in nanoscale. Simulations are takeover thin metal film irradiated by the ultrashort laser pulse. The first simulation is based on the Boltzmann transport equation and solved using the lattice Boltzmann method. The second applied method was the finite difference method with a two-temperature model. Results of both simulations were compared with experimental data what is presented in Calculations.
