摘要：

The ultrafast athermal relaxation of hot electrons in free electron metals after excitation with an ultrashort optical pulse is modelled using the linearized Boltzmann equation including the effect of electron-electron and electron-phonon scattering terms. In this paper we compare analytical predictions for the total electron energy and number density under spatially homogeneous conditions to numerical solutions obtained with a Monte Carlo technique. The numerical solutions confirm the accuracy of the analytical solution for times τE, the energy relaxation time of the electrons.
