Highly efficient lasing and thermal properties of Tm:YO and Tm:(Y,Sc)O ceramics.

We report on thermal, spectroscopic, and laser properties of transparent 5 at.% Tm-doped yttria and "mixed" yttria-scandia ceramics fabricated by vacuum sintering at 1750°C using nanoparticles produced by laser ablation. The solid-solution (TmYSc)O ceramic features a broadband emission extending up to 2.

The influence of the Sc dopant on the transmittance of (Y, Er)AlO ceramics.

High erbium content yttrium aluminum garnet (Er:YAG) and yttrium scandium aluminum garnet (Er:YSAG) ceramics have been fabricated from Er:YAG and Er:YSAG powders, respectively. The powders have been synthesized a reverse precipitation technique, processed by uniaxial pressing followed by cold isostatic pressing, and sintered in a vacuum. TEOS (tetraethoxysilane) was used as a sintering additive.
