Quantum Beat Detection by Photon Statistics Techniques
M. Á. Rebolledo, J. A. Martínez-Betorz · Spectroscopy Letters · 1989
In this paper we study the usefulness of photon statistics techniques in quantum beat spectroscopy when the intensity of the detected light beam is very small. It is concluded that accurate results can be obtained if the Fourier transform of the time-interval probability is measured.
