The Tm 3+ :KGd (WO 4 ) 2 crystal with the size up to 50 mm was grown from the K 2 O–WO 3 –BO 3 solvent system by using the top seeded solution growth method. The absorption spectrum was measured and its absorption peaks were confirmed. The emission spectra of the crystal at 455 and 665 nm were obtained when a light of 360 nm excited this crystal. A broad emission spectrum from 1650 to 2000 nm was obtained when a light of 800 nm excited this crystal. It is expected that this crystal may be useful as a tunable infrared laser crystal.
