Abstract:
The rate of energy exchange between overheated electrons and the lattice of a dielectric exposed to an ultrashort laser pulse is analyzed in the case of electron scattering by the deformation potential of acoustical phonons and the polarization potential of optical phonons. The temperature and concentration dependences of the emerging heat flux are determined, and analytical approximating expressions are proposed. Estimates for silica are given.
