Paper Abstract

The Nd3+,Cr4+ co-doped GGG epitaxial thin films for self Q-switched waveguide laser has been fabricated by a two-target pulsed laser deposition method. Concentrations of Nd and Cr ion in Nd,Cr:GGG thin films are well adjusted by changing laser ablation fluences independently for Nd:GGG and Cr,Ca:GGG sintered targets. The structure of Nd,Cr:GGG thin films on YAG substrate shows a planar waveguide structure. It is confirmed that Nd3+ and Cr4+ ions are optically active as laser active ions and saturable absorbers around 1.06 micrometers .
