Paper Abstract

In this paper we present experimental results on several features of optically excited alkali atoms. We describe small signal gain measurements including spatially-resolved gain in atomic Cs. We discuss observations of numerous near- to mid-IR emissions from states that are higher in energy than the pump beam photons. Finally we outline a measurement scheme to determine the threshold pump intensities for two types of optically excited alkali lasers.
