摘要
Using the quantum electrodynamical theory the photon statistics has been established for a single-mode laser. A general master equation is advanced and, on the basis of the steadystate photon-number distribution, the variation of the Mandel factor with the relative pumping parameter is calculated. Our results show thai photon statistics for a single-mode laser have a novel feature, i.e. the photon-number distribution alternates, in general, between superPoisson distribution and sub-Poisson distribution, and approaches the usual Poisson distribution when the pumping parameter tends to infinite. The dependence of photon statistics on detuning, coupling coefficient, absorption coefficient, thermal mean photon-number and coupling time is discussed.
