Experimental station for table-top time- and angle-resolved photoelectron spectroscopy – EXPERTISE

Understanding the microscopic mechanisms that drive the laser induced ultrafast spin dynamics (LI-USD) is one of the hottest topic in magnetism. Recent works have evidenced that they depend intimately on the electronic band structure in the laser excited state. Tackling the fundamental processes of LI-USD by studying the electronic properties of magnetic materials in the laser excited state is a promising approach to settle the controversies in “femtomagnetism”. Therefore, I aim at setting a table-top pump-probe experiment dedicated to systematic investigations of laser induced ultrafast electron and spin dynamics in ultrathin magnetic layers. It consists in developing a source of linearly polarized fs X-UV pulses and in upgrading an existing ultra-high vacuum experimental station. In its final configuration, this set-up will allow to perform spin- time- and angle-resolved Photoelectron Spectroscopy and time-resolved magnetic linear dichroism in core-level photoelectron spectroscopy.
