Crystallography, Spectroscopic Analysis, and Lasing Properties of Nd(3+) :Y3Sc2Al3O12
Abstract
The crystallographic, optical, and spectroscopic properties of Neodymium(3+):Yttrium scandium aluminum garnet are reported from which an assessment can be made regarding the material's potential as a laser. Individual Stark levels for many of the (2S+1)Lj manifolds of Nd(3+) (4f3) in the crystal have been identified from emission and absorption data up to 17,600/cm at 14K. 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. Branching ratios and diode- array-pumped laser slope efficiencies are also reported. We conclude that Nd(3+) :YSAG has potential as a diode-pumped 1-micrometer laser material. (JG)
