2023-06-07 Reconstruction of the multi-wavelength high order harmonic wavefront based on ptychography doi:10.57760/sciencedb.08147 en Diffraction patterns are obtained by using unknown high order harmonic probes to illuminate a specific sample. An improved mixed-state ptychography algorithm is used to reconstruct the multi-wavelength high order harmonic wavefront, thus enabling the characterization of high order harmonic in the space domain.X is the two-dimensional probe's one-dimensional data horizontal coordinate (in pixels) after taking the center line.ProbeOrig is the true complex amplitude of multi-wavelength high order harmonic wavefront.Aperture is the complex amplitude reconstructed by the ptychography algorithm.Model is the two-dimensional distribution of the specific sample, with the real and imaginary parts corresponding to phase changes and absorption.Lamda is the wavelength of each order of the high order harmonics. high order harmonic; ptychography; phase retrieval; multi-wavelength Meibo Zeng Zhinan PUBLIC https://creativecommons.org/publicdomain/zero/1.0/ dataset Science Data Bank
