Second harmonic generation (SHG) microscopy is a label-free, nonlinear optical imaging technique that exploits the frequency-doubling of incident photons in non-centrosymmetric structures. It provides ...

A research team led by Professor Sheng Zhigao at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has, for the first time, observed the strong nonlinear magnetic second ...

In the field of nonlinear optics (NLO), deep-ultraviolet (DUV) NLO crystals have garnered attention due to their crucial role in all-solid-state lasers. With ongoing research, the demand for these DUV ...

Plasmonic resonances have opened new opportunities to manipulate nanoscale light–matter interactions, allowing to overcome the inherent limitations of natural materials. This field was pioneered by ...

High-order harmonic generation (HHG) — a technique that converts light into much higher frequencies — is an essential tool for exploring otherwise inaccessible parts of the electromagnetic spectrum.
