Paper Abstract

We show that, with favorable spontaneous emission damping rates, substantial steady state population inversions can be created in coherently pumped multilevel systems. We relate the conditions to achieve inversion to the phenomenon of effective Rabi cycling between separated levels in a ladder coupling scheme and to a detailed balance obtained with damping rates between levels mixed by the Rabi cycling. We consider the inversion process and the process of energy extraction into a cavity for a five level system with realistically chosen parameters. We show that the system behaves very much like a conventional laser, resulting in a device with output at frequency near the sum of the pump frequencies.
