Off-resonant operation of a double-transition single-mode laser
Sun Son-gen, Xiao-shen Li, Nianyu Bei · Physical Review A · 1987
Scully and Lamb's quantum theory of the laser is extended to deal with nonresonant operation of a single-mode laser in a homogeneously broadened medium consisting of three-level atoms. In the case of weak-field intensity, the master equation and operation characters such as the threshold condition, the average photon number, and the half-width of the photon distribution are obtained and discussed.
