Abstract
A broad survey is taken to assess the agility of the cesium 62D states in the generation of cascade lasing from 455 to 3650 nm. The experiment utilized a heat pipe with 0 to 10 Torr of He, cesium densities of 1014 to 1017 atoms per cm3, and it is pumped by a pulsed dye laser with 1 to 30 mJ/pulse. Cascade lasing, generated by amplified spontaneous emission with no aid of a cavity, is observed on over 17 transitions—nearly every dipole allowed transition from energy levels below 62D. Many lasing lines possess 100 to 229 μJ of energy, slope efficiencies of 4 to 7%, low thresholds favorable for diode pumping, and together have combined optical conversion efficiencies as high as 10%±3%. This agile system could have applications in infrared counter measures, target illuminator lasers, beacon lasers, underwater communication, and other tactical laser applications.
