Abstract
In this paper the polarized optical spectra (absorption and fluorescence) of the ion in the nonlinear crystal have been systematically investigated at low (10 K) and room temperature. Most energy levels of in this crystal (103) have been identified and conveniently labelled with their crystal field quantum numbers, and . The radiative emitting states have been identified. Analysing the optical absorption spectra with the anisotropic Judd - Ofelt theory, the radiative lifetimes and branching ratios from the metastable state have been calculated. Then, relevant spectroscopic parameters (quantum efficiency and emission cross sections) for laser applications have been estimated. Infrared to visible up-conversion is reported for the first time in this host crystal.
