The research group will decisively advance laser-based XUV imaging in the so-called water window central to the life sciences, in which water is comparatively transparent but highly absorbent. The project pursues two complementary approaches for powerful XUV sources that support different imaging techniques and are tested on various XUV microscopes (zone plates, ptychography, coherence tomography). In addition, methods for imaging and material analysis are optimised and the development of new detectors is also promoted.
