Absorption and site-selective laser spectroscopy of BaF2:Nd3+ single crystals

Track: Track A - Division for Condensed Matter Physics and Materials
Spectroscopic studies of Nd<sup>3+</sup> ions in BaF<sub>2</sub> single crystals have been carried out in order to determine the optical properties of the material. A single Nd<sup>3+</sup> - F<sup>-</sup> center is dominant for dopant concentrations of up to 0.1%; this homogeneity makes the material attractive as a potential laser medium. Crystal-field energy levels for several Nd<sup>3+</sup> multiplets deduced from optical absorption, direct fluorescence and upconversion fluorescence spectra obtained at 10 K will be presented and energy exchange mechanisms proposed.
