Single crystals of Cr3Sr3Ga2Ge4O14 garnets are grown by using the Czochralskimethod in Platimum-rhodium crucible. The polarised optical absorption spectra of Cr aremeasured. The schematic description on the absorped bands in visible and near-IRwavelensth is presented. We suggest that Cr enters the octahedral and tetrahedralpositions as Cr3+ and Cr4+ respectively. The near-IR absorption of Cr4+ will affect theluminescence of Cr3+.
