Photon correlations in the cooperative radiation from a continuously and incoherently pumped three-atom system
Th. Richter · Journal of Physics B Atomic and Molecular Physics · 1982
The intensity correlation function of the cooperative radiation from a continuously pumped three-atom system is calculated using Lehmberg's master equation supplemented by an incoherent-pumping term. Cooperative effects are found to change drastically the intensity fluctuations of the emitted radiation. Particularly, if the pumping rate is adjusted to three times the single-atom spontaneous decay rate, increased radiation, compared with that from three independently emitting atoms, should be observed, exhibiting a reduced intensity fluctuation.
