Lattice deformation from interaction with electrons heated by ultrashort laser pulse
We propose a model describing destruction of metals under ultrashort intense laser pulses when heated electrons affect the lattice through the direct electron-phonon interaction. The metal consists of hot electrons and cool lattice. The lattice deformation is estimated immediately after the laser pulse up to time of electron temperature relaxation. The hot electrons are described with help of Boltzmann's equation and the equation of thermoconductivity. We use equation of motion for lattice displacements with the electron force included. The estimate of lattice deformation shows that the ablation regime can be achieved. PACS: 62.20.Fe, 63.20.-e, 79.20.Ds
