Pietro Carrara is currently working at SPRINT Laboratory high harmonic generation beamline. His activity is mostly devoted to the implementation and optimization of the XUV source from High Harmonics Generation in gas phase, starting from a mode-locked pulsed IR laser, used for time-resolved photoemission experiments. He is also developing a new set-up for Transient Grating experiments, also with in-vacuum sample environment, exploiting the SPRINT laser sources.
