Paper Abstract

The high resolution and polarized spectroscopic investigation of Nd3+ in Mg-compensated strontium lanthanum aluminate Srl-xLax-yNdyMgxAl12-x019 (Nd: ASL) function on composition makes possible the elucidation of the nature of non- equivalent centers and enables the selection of composition and pumping conditions that grant the efficient quasi-three-level laser emission around 900 nm. Based on a proper selection of these conditions, 900 nm laser emission with slope efficiencies of 0.74 and 0.84 at 792 nm 4F5/2 and respectively 865 nm 4F3/2 pumping of Nd3+ is demonstrated.
