Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...
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 ...
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 ...
TALIF works by using a precisely tuned laser to excite the atoms being measured. Instead of absorbing a single photon, each atom absorbs two photons at the same time, and the combined energy of these ...
