Ever since the first observation of high-order harmonics generation (HHG) 1,2,3,4 using ultrashort ultraviolet (UV) and infrared (IR) laser pulses, this extreme nonlinear upconversion phenomenon has ...
The proposed computational framework for RFD-based CDIs is shown in Fig. 1b–d. In such lensless geometries, the measured signal is typically a diffractogram (or a sequence of such). The measured ...
Researchers from the University of Science and Technology of China (USTC) have unveiled a planar optical device that significantly enhances the capabilities of dark-field microscopy, achieving ...
