The interplay between high-harmonic generation and photoluminescence in ZnO: Anisotropic spectral properties of harmonic emission and the role of excitons
Simon P. S. Jessen, Mark Mero, Marc J. J. Vrakking +3
We investigate the nonlinear optical response of bulk ZnO under intense short-wave infrared excitation, focusing on the interplay between high-harmonic generation (HHG) and photolu…

Laser-induced transient opacity in helium nanodroplets probed by single-shot coherent diffraction
Julian C. Schäfer-Zimmermann, Tom von Scheven, Katharina Kolatzki +13
Single-shot coherent diffractive imaging (CDI) with intense short-wavelength light pulses enables the structural characterization of individual nanoparticles in free flight with hi…

Plasma formation and relaxation dynamics in fused silica driven by femtosecond short-wavelength infrared laser pulses
P. Jürgens, M. J. J. Vrakking, R. Stoian +1
Laser-induced plasma formation and subsequent relaxation in solid dielectrics is the precursor to structural modifications that are accompanied by a permanent alteration of materia…
