A recent study has unveiled a transformative nonlinear optical metasurface technology. This new technology, characterized by structures smaller than the wavelength of light, paves the way for ...

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 optics describes the regime in which the response of a material to an applied electromagnetic field depends nonlinearly on the field amplitude. Whereas in linear optics the induced ...

Nonlinear optical phenomena in organic and molecular materials arise from the interplay of electron delocalisation, molecular asymmetry and supramolecular order, yielding large hyperpolarizabilities ...

Nonlinear optics has long relied on high-power lasers, whose spatial and temporal coherence ensures efficient nonlinear frequency conversion. However, a new study challenges the traditional assumption ...

Researchers at the University of California, Los Angeles (UCLA) have developed an optical computing framework that performs large-scale nonlinear computations using linear materials. Reported in ...

A standard digital camera used in a car for stuff like emergency braking has a perceptual latency of a hair above 20 milliseconds. That’s just the time needed for a camera to transform the photons ...

Ultrafast optical measurements expose buried crystal flaws in atom-thin insulating films, offering a non-destructive route to ...

You wouldn’t think that shaking something in just the right way would be the recipe for creating laser light, but as [Les Wright] explains in his new video, that’s pretty much how his DIY Raman laser ...
