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 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 Yb:YAG, thin-disk laser technology.
In the second part of my talk, I show the first proof of principle sampling of the electric field of light at PHz frequency in ambient air by means of electro-optic sampling and discuss the potential of the technique in molecular spectroscopy and imaging.
