Abstract

Y3Al5O12 single crystals codoped with ytterbium and chromium were successfully grown by the Czochralski method. The effects of growth atmosphere, annealing temperature, the initial Cr content in the melt, and Ca/Cr ratio on the absorption characteristics of tetravalent Cr4+ have been evaluated. The fluorescence lifetimes of Cr, Yb:YAG with various concentrations of Cr and Yb:YAG were measured. The optimum annealing temperature, initial Cr content in the melt, and Ca/Cr ratio are given.
