Subcollisional linewidth observation in the coherent-population-trapping Rb maser
Abstract
We report the observation of the 87Rb ground-state hyperfine transition with a subcollisional linewidth performed in a cell with buffer gas. The transition is observed as a coherent-population-trapping maser-emission profile excited by means of a Λ interaction scheme in the high-atomic-density regime. A theoretical explanation of the phenomenon is given in good agreement with the observed linewidth behavior.
