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 ...
Photon upconversion involves a series of non-linear optical processes where the sequential absorption of two or more photons leads to the emission of a single photon with energy greater than the sum ...
