Speaker
Description
The aim of this talk is to present the activity of CNR-IFN and the Physics Department of Politecnico di Milano on ultrafast spectroscopy within the SMART-X network.
Ultrafast X-ray spectroscopy allows the study of light-matter interaction with unprecedented temporal and spatial resolution with the further advantages of being element-selective and oxidation- and spin-state specific. The investigation of the properties of core electrons at ultrafast time scales promises to enlighten the dynamics occurring in complex materials. I will discuss the recent developments we implemented toward attosecond X-ray spectroscopy based on tabletop sources. In particular, I will present the development of the transient absorption/reflectivity beamline for the study of materials based on efficient high-order harmonic generation in fused-silica chips fabricated by femtosecond laser micromachining. I will also present recent results on HHG spectroscopy from germanium crystals.
