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 ...

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 ...

New approach offers great potential for ophthalmic diagnostics and AR/VR applications. “Two-photon vision offers great potential for ophthalmic diagnostics”. Scientists at ICTER, the International ...
