摘要：

We determine the conditions under which a four-level medium in a resonant cavity can start lasing when there is no population inversion between the lasing levels. The mechanism which is used is the creation of low-frequency coherence by a pair of external pump fields. it is shown that lasing with frequency upconversion requires population inversion at (low-frequency) nonlasing transitions. © 1990.
