Abstract
The crystallographic, optical, and spectroscopic properties of are reported from which an assessment can be made regarding the material’s potential as a laser. Individual Stark levels for many of the manifolds of (4) in the crystal have been identified from emission and absorption data up to 17 600 at 14 K. The observed crystal-field splitting and the measured cross sections (intensities) associated with manifold-to-manifold transitions are compared with calculated splittings and calculated intensities. The crystal-field and Judd-Ofelt intensity parameters were calculated for Nd and all other rare-earth ions. Branching ratios and diode-array-pumped laser slope efficiencies are also reported. We conclude that : has potential as a diode-pumped one-micrometer laser material.
