The Ultrafast dynamics in matter (UdynI) group is a joint research group between the Istituto di Fotonica e Nanotecnologie of the Italian National Research Council (CNR-IFN) and the Physics Department of Politecnico di Milano. Their research is focused on attosecond science and ultrafast spectroscopy. The group is led by Caterina Vozzi.
Research Activity
- Ultrafast THz Spectroscopy
- Ultrafast THz Spectroscopy is a state-of-the-art technique that encompasses the study of light-matter interaction with an unprecedented temporal and spatial resolution. Ultrafast means times in the femtosecond and attosecond scale. It revolves around the generation of isolated attosecond light pulses and their phase matching.
- Attosecond Science
- In Attosecond Science, these aforementioned pulses excite and probe matter on the temporal scales typical of electron dynamics. The sample is excited by two signals, one from the pump exciting carriers in the valence band and one from the probe exciting carriers in core orbitals, with a delay in respect to the first one. The signal is then measured with a spectrometer which produces either absorption or reflectivity spectra.
- High Harmonic Generation (HHG) spectroscopy
- Pulse generation is based on High-order Harmonic Generation (HHG). HHG is a strongly non-linear optical process which involves the emission of coherent radiation, co-linear to the pump, with a characteristic comb-like spectrum of odd harmonics of the fundamental laser field.
