Paper Abstract

The interaction of picosecond laser pulses with solid surfaces is characterized by ultra-fast energy transfer from the electronic system to the lattice. The present understanding of the elementary mechanisms responsible for carrier thermalization and cooling is briefly reviewed. In semiconductors, the electron hole plasma acts as intermediate energy storage. Recombination limits the maximum density and determines lattice heating in degenerate conditions. Experiments with femtosecond and picosecond laser sources have unraveled the salient features of the energy dissipation routes from photons to lattice.
