Frequency-shifted cavity emission on the same transition is observed and is found to require a threshold pump intensity and atom number; moreover, the emitted light shows a flat $g^(2)$ correlation function. These facts indicate lasing action via a three-photon process including pump and trap beams, related to effects previously found in cold Rubidium clouds, but also pronouncedly different. We characterize the conditions and properties of this process and present a model.
