Two-photon absorption (2PA) is a third-order non-linear optical process in which a molecule simultaneously absorbs two photons of lower energy to reach an excited electronic state. This phenomenon has ...

In a development that could reshape the future of microelectronics, optics, and biomedicine, researchers from Jinan University, in collaboration with the Institute of Chemistry at the Chinese Academy ...

Photonic systems are quickly gaining traction in many emerging applications, including optical communications, lidar sensing, and medical imaging. However, the widespread adoption of photonics in ...

Two-photon absorption (TPA) is a non-linear optical phenomenon in which a molecule simultaneously absorbs two photons, promoting it from the ground to an excited electronic state. Dependent on the ...

A cutting-edge experiment has revealed the quantum dynamics of one of nature's most crucial processes. Using a complex cast of metal-studded pigments, proteins, enzymes, and co-enzymes, photosynthetic ...

X-ray backscatter AIT uses a narrow beam of X-ray photons with energies, hv, less than 100 keV. 2 There are five basic interactions that can occur as X rays penetrate material. These are the ...

A new dual-comb LiDAR technique creates micron-scale 3D images of tiny metal objects, enabling precise non-contact inspection ...
