Atomic force microscopy (AFM) has long served as a cornerstone technique for nanoscale imaging and surface characterisation. Recent advances in noncontact AFM have increasingly harnessed the ...

When light passes through a material, it often behaves in unpredictable ways. This phenomenon is the subject of “nonlinear optics”, which is now integral to technological and scientific advances – ...

A research team affiliated with UNIST has announced the development of an innovative nonlinear imaging technique capable of visualizing internal biological tissues in 3D using ordinary light sources, ...

Nonlinear Raman microscopy techniques, such as coherent anti-Stokes Raman scattering and stimulated Raman scattering, are widely used to provide chemical and spatial information. A third nonlinear ...

When light goes through a material, it often behaves in unpredictable ways. This phenomenon is the subject of an entire field of study called “nonlinear optics”, which is now integral to technological ...

have found a new way to image layers of boron nitride that are only a single atom thick. This material is usually nearly invisible in optical microscopes because it has no optical resonances. To ...

Nonlinear optical dynamics—intensity-dependent response of light upon interaction with materials under high-intensity light sources—are of huge significance in modern photonics, finding applications ...

Two-photon microscopy is a type of fluorescence microscopy that, rather than exciting the sample with a single photon, makes use of multiple photons. The advantage over more traditional one-photon ...

Researchers developed a 3D imaging method that visualizes internal tissues using ordinary light sources instead of expensive ultrafast lasers. (Nanowerk News) A research team, affiliated with UNIST ...
