Optically pumped far infrared lasers
Abstract
Experiments and theory regarding the emission processes in optically pumped far infrared laser sources are reported. Super-radiance from CH3F at 496 micrometers in the homogeneously broadened regime has been identified for the first time. Stimulated Raman emission on pure rotational transitions in D2O at 50 and 66 micrometers has also been identified for the first time. Generally good agreement between experiments and a Maxwell-Bloch approach was obtained for the super-radiance study, and good qualitative agreement between experiments and a Maxwell-density matrix approach using three waves interacting in a four-level system was noted for the Raman study; both implying that the processes are now reasonably well characterized and understood.
