ABSTRACT:
A tunable alkali metallic vapor laser system is disclosed. Stimulated Raman scattering (SRS) in a low pressure atomic alkali metallic vapor of potassium or cesium is utilized wherein the atomic vapor is provided and then primed to populate an intermediate level such as the 4P.sub.1/2 level for potassium and the 6P.sub.1/2 level for cesium from which the desired upper laser level is accessible. After the population is created at the intermediate level, it is pumped to a virtual level near the desired upper laser level by a tunable dye laser and, via the SRS process, generates the tunable output laser beam.
