Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...

Nonlinear excitation can be categorized into two types: natural and artificial. The natural type arises from the intrinsic nonlinear response of the material, while the artificial type stems from the ...
