Paper Abstract
We perform two-colour pump probe experiments on metals and superconductors using synchronized 10-fs pulses
generated by optical parametric amplifiers, tunable from the visible to the near-infrared, mapping with unprecedented
detail the energy equilibration dynamics of the free electron gas. In gold films we observe dramatic changes of the
differential reflectivity spectrum on the 100-fs timescale, corresponding to the establishment of the thermal electron
distribution, with dynamics dictated by excess energy. In high-Tc cuprate superconductors we observe fast electron
relaxation, attributed to a strong electron-phonon coupling which may play a role in the superconductivity mechanism.
