Elphos laboratories have been developed by integrating modern ultrafast laser sources with an angle-resolved photoemission equipment and broadband optical spectroscopy techniques. We are currently able to investigate the non-equilibrium electron dynamics in solid-state systems through time- and angle-resolved non-linear photoemission and to perform high resolution time-and frequency-resolved optical spectroscopies.
