Ultrafast laser-driven phase transitions of solids are a challenging field of research. After excitation with a femtosecond laser pulse the system is usually far from equilibrium and can therefore not be described on a thermodynamic basis. In order to explain non-equilibrium phase transitions and identify the dominant microscopic mechanisms it is imperative to follow the transient states that are involved in the dynamics.
To this end we will recommission a tabletop high-order harmonic setup for time- and angle-resolved photoelectron spectroscopy in the XUV regime. With photon energies up to 45eV it will be possible to examine the valence bands and outer core levels of the sample system.
