Femtosecond Three-Photon Counting in a Photomultiplier Tube
Amir Nevet, Alex Hayat, Meir Orenstein · Advanced Photonics · 2011
We demonstrate experimentally ultrafast three-photon counting by three-photon absorption in a photomultiplier tube, which may serve as a unique tool for ultrafast quantum state characterization as well as for ultrasensitive temporal measurements.
