Abstract

The interaction of picosecond laser pulses with solid surfaces is characterized by ultrafast energy transfer from the electronic system to the lattice. Heating and melting occur in the picosecond time scale. In semiconductors, the transfer is mediated by the electron hole plasma. Its kinetics is dominated by nonlinear recombination mechanisms that reduce considerably the maximum carrier concentration at high irradiation levels. Experiments with time resolved optical and photoelectrical techniques have established firm evidence for ultrafast thermal surface heating and rapid carrier recombination.
