EE Devices Seminar - Hanieh Fattahi, MPI

Thursday May 26, 2022 2:00 PM

Spectro-microscopy at Extreme Limits

Speaker: Hanieh Fattahi, Femtosecond Fieldoscopy, Max Planck Institute for the Science of Light
Location: Chen 100

This talk is devoted to modern methods for attosecond and femtosecond laser spectroscopy, with a special focus on applications that require spatial resolution. In the first part, I discuss two of the long-standing challenges in attosecond spectroscopy: i) the required photon flux for XUV pump-XUV probe spectroscopy, and ii) the necessary ultra-high spatiotemporal resolution for resolving electron-dynamic in the matter. High harmonic generation by high-energy, high-power light transients holds promise to overcome both barriers. I demonstrate our effort in this direction and the first prototype field-synthesizer based on ytterbium, thin-disk laser technology

In the second part of my talk, I show the first proof of principle field-resolved detection of few-cycle pulses at PHz frequency and in ambient air and discuss the unique potential of the technique for molecular spectroscopy and imaging.
