Abstract

Developing efficient Er³⁺,Yb³⁺:YAG eye-safe lasers is a priority of modern laser technology. This paper focuses on the influence of the concentration of Yb³⁺ ions on the spectroscopic properties of Er³⁺,Yb³⁺:YAG transparent ceramics. Four samples with different concentrations of Yb³⁺ ions were prepared by solid-state reaction sintering. The study revealed the influence of Yb³⁺ ions on the microstructure and the sintering process. A high concentration of Yb³⁺ ions leads to the formation of Y³⁺-rich impurity phases and causes segregation of Er³⁺ and Yb³⁺ and Si⁴⁺ into these phases. The influence of Yb³⁺ ions on the shape of emission spectra and the lifetimes of both Er³⁺ and Yb³⁺ ions was shown. Changes in the spectroscopic properties were ascribed to increase in neat transfer between Yb³⁺ and Er³⁺ ions. IQE of Er³⁺ and Yb³⁺ luminescence were calculated, and optimal Er³⁺/Yb³⁺ ions ratio were proposed.

期刊介绍： The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
