Measuring the dipole phase of Bloch-trajectory harmonics using a monolithic interferometer
Mohanad Awad, Julian Späthe, Paramjit C. Yadav +10
Uncovering the dipole phase of gas-phase high harmonic generation was instrumental to understanding the recollision physics underlying attosecond pulse generation. Corresponding me…

Laser-driven high-flux source of coherent quasi-monochromatic extreme ultraviolet radiation for coincidence spectroscopy
Julian Späthe, Sebastian Hell, Martin Wünsche +6
We present a source of coherent extreme ultraviolet (XUV) radiation with a flux of 10 photons per second at 26.5 eV. The source is based on high-harmonic generation (HHG) in…

Exploring Valence Electron Dynamics of Xenon through Laser-Induced Electron Diffraction
Fang Liu, Slawomir Skruszewicz, Julian Späthe +11
Strong-field ionization can induce electron motion in both the continuum and the valence shell of the parent ion. Here, we explore their interplay by studying laser-induced electro…
