Abstract

Lasing on the D₂ (6p P2 3/2 →6s S2 1/2) transition of atomic Cs at 852.1 nm has been observed with a four level system in which the Cs 6p P2 3/2 state is pumped by the photoassociation and subsequent dissociation of Cs-rare gas collision pairs. Characterized by a quantum efficiency >98%, this laser requires no atomic precursor to the upper laser level and provides oscillation on an alkali transition inaccessible to three level, photopumped alkali laser systems. Measurements of photoabsorption and pump energy threshold in Cs-Ar-Kr mixtures reveal the influence of three body photoassociation.
