Abstract
Amplified spontaneous emissions (ASEs) of the Na2 violet, K2 yellow, and Rb2 orange diffuse bands, which are potentially important in the development of continuously tunable high-power laser sources, were observed from electron-beam-excited mixtures of Na-Na2, K-K2, or Rb-Rb2 vapor with argon buffer gas. The continuum spectra centered at 436, 574, and 604 nm were attributed to triplet-triplet Na 2, K2, and Rb2 bound-free transitions, respectively. The dissociative recombination reaction of Na3 +, K3+ or Rb3+ is discussed as an efficient formation process of the upper states in the present electron beam pumping experiments
