Crystals of yttrium aluminum garnet (YAG) doped with tetrahedrally coordinated V 3+ ions were grown using the Czochralski method in a highly pure argon atmosphere. The absorption and transmission spectra of trivalent vanadium in YAG crystals have been measured at room temperature. Seven bands were observed in which two bands centered at 370 nm (27027 cm –1 ), 800 nm (12500 cm –1 ) are reported for the first time. We also present the crystal‐field calculations of tetrahedrally coordinated V 3+ impurity systems in YAG crystal. These calculation results are in good agreement with the optical experiment data.
