Fig. 5: EUV experimental validation using tabletop HHG source.

a The spectrum of an EUV HHG source. b Polychromatic diffraction pattern obtained by the source. c Reconstructed amplitude of osteosarcoma cells using traditional ePIE. d Reconstructed amplitude of the same sample using ultra-broadband ePIE. The scale bar in (d) corresponds to 25 μm.
