Sub-Poissonian Statistics of Fluorescence from a Single Atom Driven by a Continuous Wave Laser Field

摘要: Statistics of fluorescence photons emitted by a single two-level atom interacting with continuous wave laser field are analyzed. The photon-counting distribution is calculated for the so-called intermediate photons, i.e., those counted during time interval between instants at which emitted. result sub-Poissonian (narrower than Poisson) distribution, agrees experimental observations. This intermediate-photon used to calculate average number second factorial moment and Mandel’s Q parameter commonly evaluate deviation photon statistics from Poisson distribution. theoretical expressions obtained moments different well-known formulas.
