Paper Abstract

Strontium lanthanum aluminates crystals (ASL) doped with Nd3+ with formula Sr1-xNdyLax-yMgxAl12-xO19 are interesting crystals for lasers operating in i.r. (~900 nm range) or blue spectral ranges. This paper uses high-resolution spectroscopy, at low temperatures, for investigation of the influence of composition and Nd3+ doping of ASL crystals on emission properties. Preliminary spectral characteristics of two non-equivalent centers were determined. From these data and their dependence on composition, structural models for the two centers are proposed.
