Ulysses laboratories intragrate the modern ultrafast laser sources with the traditional optical spectroscopic techniques. We are currently able to investigate the non-equilibrium electron dynamics in solid-state and bilogical systems through high resolution time- and frequency-resolved optical spectroscopies.
