摘要:
A general expression for stimulated transition rates between two levels of an atomic system is developed. This expression not only applies for an arbitrary radiation field, but it also includes the effects of line broadening on transition rates. The general expression is used to obtain the rate equation for the spectral photon number density per steradian for a given pair of atomic energy levels. The result is applied to two special cases by integrating over the spectral and angular ranges of interest.
