Attosecond high-harmonic interferometry probes orbital- and band-dependent dipole phase in magnesium oxide
Nataliia Kuzkova, Pieter J. van Essen, Brian de Keijzer +3
Control over the spatial coherence, wavefront, and focusability of emitted light relies on understanding the intrinsic phase of the emission process, and vice versa, measuring phas…

Spatial polarization gating of high-harmonic generation in solids
Pieter J. van Essen, Brian de Keijzer, Tanya van Horen +4
High-harmonic generation from solids can be utilized as probe of ultrafast dynamics, but thus far only over extended sample areas, since its spatial resolution is diffraction-limit…
