Subpixel correction of diffraction pattern shifts in ptychography via automatic differentiation
Zhengkang Xu, Yanqi Chen, Hao Xu +10
Ptychography, a coherent diffraction imaging technique, has become an indispensable tool in materials characterization, biological imaging, and nanostructure analysis due to its ca…

Multiscale carrier-envelope phase characterization of 2-μm pulses delivered by a 200-kHz optical parametric amplifier
Katrin Meier, Arvid Klösgen, Kerstin Harland +7
Light fields with a central wavelength of 2 um are very well suited for strong-field-driven charge carrier control: Their photon energy lies far below the band gap of many material…
