Abstract

We present a novel approach involving spatially resolved Fourier transform spectroscopy (FTS) combined with diffractive shear interferometry (DSI) prior to ptychographic measurements, in which a pair of HHG pulses with varying time delay is used in a ptychography scan. Through this scheme, we vastly increase wavelength diversity, improving multi-wavelength reconstructions.
