Development of an experimental setup for ultrafast imaging with high harmonics — •Michael Lohmann, Sergey Zayko, Ofer Kfir, and Claus Ropers — 4th Physical Institute - Solids and Nanostructures, University of Göttingen, 37077 Göttingen, Germany

High-harmonic generation (HHG) is a unique source for spatially resolved quantitative studies of nanoscale polarisation anisotropies [1] leading to high-resolution magneto-optical imaging using lensless techniques [2]. However ultrafast HHG imaging remains challenging.

Here, we present the development of a pump-probe setup to extend the capabilities of our HHG-microscope for comprehensive studies of ultrafast dynamics in nanostructured solids. Combining nanometer spatial with femtosecond temporal resolution, this instrument will provide for further insights into ultrafast processes in materials science, including ultrafast magnetism.
