Abstract

Single crystals of Cr,Ca:Y3Al5O12(YAG)were grown by the Czochralski (CZ) method. The aborption characterization of both as-grown and oxygen-annealedcryStals was carried out and compered with each other. Every absorption peak of Cr4+ and Cr3+ increased in intensity by annealing. It's also found that the main band position of Cr 3+ was red shifted. These phenomena and formation mechanism were analyscd anddiscuss.
