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.
