Optical fiber, as the basic carrier of modern high-speed and high-capacity communication, is the key to the interconnection of the world. With the rapid development of the communications industry in ...

Coherent anti-Stokes Raman scattering (CARS) is a versatile tool to investigate the molecular composition of biological and non-biological samples, such as cells or mammalian tissue 1,2. Combining ...

Tunable Bessel beam two-photon fluorescence microscopy enables high-speed volumetric intravital imaging of subcellular dynamics within living mouse brains with fully tunable spatial resolution and ...

Orbital angular momentum (OAM) describing the “phase twist” (helical phase front) of light beams 1, has recently gained increasing interest due to its potential applications in many diverse areas ...

SEM is a common microscopy technique for scanning a surface. In SEM, a beam of high-energy electrons is fired from an electron gun towards a sample of interest. The beam of electrons is controlled by ...
