Coherent Properties of the Two-Photon Coherent State

Abstract

Photon anti-bunching of the two-photon coherent state (TCS) is investigated under the variation of parameters. It appears that the effect of anti-bunching is less for stronger intensity of the radiation. Since two-photon laser has not been realized yet, detection or the TCS should be carried out for the radiation through matter in which as a result of interaction the TCS might be created, i.e., hybrid radiation containing the TCS. The second-order coherence of the hybrid radiation consisting of TCS and blackbody radiation is discussed. Numerical results are shown in several figures.
