A MODEL FOR THE PRODUCTION OF REGULAR FLUORESCENT LIGHT FROM COHERENTLY DRIVEN ATOMS

It has been shown in recent years that incoherent pumping through mult iple atomic levels provides a mechanism for the production of highly a nti-bunched light, and that as the number of incoherent steps is incre ased the light becomes increasingly regular. We show that in a resonan ce fluorescence situation, a multi-level atom may be multiply coherent ly driven so that the fluorescent light is highly anti-bunched. We sho w that as the number of coherently driven levels is increased, the spo ntaneous emissions may be made increasingly more regular. We present a systematic method for designing the level structure and driving requi red to produce highly anti-bunched light in this manner for an arbitra ry even number of levels.
