Alkali-Vapor Light Sources as Optical Pumps for Nd: YAG.
Abstract
Pulse-operated light sources containing cesium (Cs), rubidium (Rb), potassium (K), sodium (Na), and a Na-Rb mixture were evaluated for efficiency as optical pumps for Nd:YAG. The results are compared with those obtained from conventional xenon (Xe) and krypton (Kr) flashlamps. The Na-Rb mixture has a maximum efficiency over the four broad pumping regions of Nd: YAG that is twice as large as that of Xe, when operated under similar conditions of keep-alive field and pulse power. Na and K are highly competitive with both Xe and Kr. Cs and Rb appear attractive at low pressures (20 torr) and low pulse power inputs (2 kW). (Author)
