  • Abstract
    The polarized absorption spectra, emission spectra, and fluorescence dynamics of Cr:forsterite are presented and analyzed in detail. At least three different kinds of emitting centers are identified by time-resolved spectroscopy. These correspond to two sorts of octahedrally coordinated Cr3+ ions and one Cr4+ with various possible environments. The infrared laser active center is identified with the latter species, and its infrared absorption and emission properties are attributed to excited state-ground state optical transitions without any thermalization process into the excited state
