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 (PLD) method. The concentrations of Nd and Cr ion in the co-doped GGG thin films are well controlled by changing respective KrF laser ablation fluence and repetition rate 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 with high numerical aperture. It is confirmed that Nd3+ and Cr4+ ions are optically active as laser active ions and saturable absorbers respectively at 1.06 micrometer to be used for monolithic self-Q-switched waveguide laser to generate high peak power and short pulse output.
