Resumen:
A systematic investigation of the optical absorption of the Nd3+ ion in the Ca3Ga2Ge3O12:Nd3+ garnet (CGGG:Nd) crystal is presented. An assignment of the Stark energy levels was carried out assuming a D2 symmetry site for the Nd3+ ions in CGGG:Nd. Some relevant spectroscopy parameters for laser applications: radiative lifetime, branching ratios and quantum efficiency from the 4F3/2 emitting state were estimated using the Judd-Ofelt theory.
