Multiphoton coincidence spectroscopy
L Horvath, B C Sanders, B F Wielinga · Journal of Optics B Quantum and Semiclassical Optics · 1999
We extend the analysis of photon coincidence spectroscopy beyond bichromatic excitation and two-photon coincidence detection to include multichromatic excitation and multiphoton coincidence detection. Trichromatic excitation and three-photon coincidence spectroscopy are studied in detail, and we identify an observable signature of a triple resonance in an atom-cavity system.
