Abstract
Absorption spectra for alkali-rare gas spectral satellites and alkali dimers in potassium, rubidium, and cesium are presented. Previous investigations of alkali-rare gas spectral satellites are incomplete, causing many of these satellites to remain unidentified or ill-characterized in the literature. The data presented in this work were captured by illuminating heated alkali vapor-rare gas cells with a xenon lamp and recording the spectra using a Yokogawa 6370D Optical Spectrum Analyzer. To generate a sufficient alkali vapor number density to observe satellites, the cells were placed in an oven and heated to temperatures between 353 K and 513K. The knowledge of alkali-rare gas blue satellites has the potential to be significant for the creation of low-divergence, high-power lasers for application as directed energy weapons and in anti-missile defense measures.
