"The quest for an Ångström-resolution and Attosecond-speed tabletop camera"

Laser-driven bright coherent ultrafast soft X-ray pulses, produced via the mechanism of higher-order harmonic generation (HHG), are important for time- and frequency-resolved spectroscopy of materials and molecules and would enable numerous applications in bio- and nano-structure imaging. Methods for increasing the HHG photon flux in the water-window and in keV spectral ranges from neutral noble gas targets have been subject of intense theoretical and experimental efforts for over a decade. The talk will present the latest experimental advances in HHG driven by single and multicolor mid-IR pulses fields and discuss the promise of such schemes for extending the cut-off photon frequencies into the multiple keV range.
