Abstract content <br> &nbsp; (Max 300 words)

Spectroscopic studies of Nd3+ ions in BaF2 single crystals have been carried out in order to determine the optical properties of the material. A single Nd3+ - F- 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 Nd3+ multiplets deduced from optical absorption, direct fluorescence and upconversion fluorescence spectra obtained at 10 K will be presented and energy exchange mechanisms proposed.
