Fabrication of YAG/Cr:YAG transparent composite ceramics and characterization by light sheet fluorescence imaging
Résumé
Transparent composite ceramics based on YAG/Cr:YAG bilayer samples were manufactured by the solid-state reaction route and sequential slip-casting technique. They were characterized by light sheet fluorescence imaging (LSFI). This work shows that LSFI allows determining the spatial distribution of chromium with different valence state (Cr 4+ and Cr 3+) with a resolution close to 5 µm and high sensitivity in regards to the concentration. LSFI thus appears well adapted to the characterization of transparent ceramic materials with luminescent dopant gradient used as solid-state lasers optical components.
