Abstract
Using ultrafast time-resolved ultraviolet photoelectron spectroscopy, we ha ve followed the energy relaxation kinetics of conduction electrons in quart z, for energies of the order of 30 eV above the conduction-band minimum. We measure energy-loss rates three orders of magnitude lower than those estim ated for energies close to this minimum. Likewise, the impact ionization ra te obtained (1/40 ps(-1)) is much lower than the values generally assumed i n optical breakdown models.
