Generation of Light Using Two-Level Atoms with Initial Coherence

摘要

The Fokker-Planck equation for the Glauber quasi-probability is derived, which describes one-photon generation of light in lasers and micromasers using atoms with initial coherence. Stationary lasing and masing conditions are analyzed. In particular, the case of an inversionless transition is considered. The line shape and the photon statistics are found. The field state for lasing on an inversionless transition is found to be coherent.
