PHYSICS OF VIBRONIC TRANSITIONS IN THE SPECTRA OF RARE EARTH IONS IN CRYSTALS.

Abstract

Enhancement of vibronic transitions with self-trapping of the parent resonance radiation was investigated in gadolinium compounds. Optical pumping of gadolinium was tried in several host lattices for obtaining a vibronic laser. The pumping efficiency was found to be considerably below the threshold. Vibronic spectra of gadolinium assiciated with adjacent H(-) ion in CaF2 were recently observed. The assignment of this transition and the correlation with the Infra-red absorption of the H(-) ion is discussed. (Author)
