Abstract
We perform high-resolution multi-spectral wavefront sensing on extreme ultraviolet sources produced by high-harmonic generation processes. Using ptychography, we show spectrally resolved complex-valued beam reconstructions for eight harmonics simultaneously, with a spatial resolution of 1 µm.
