Abstract
Rod-shaped thulium-doped gadolinium ortho-vanadate (Tm:GdVO4) crystals have been successfully grown by using the floating zone (FZ) method. The crystals grown showed good transparency and with no cracks and bubbles. Tm:GdVO4 exhibited a strong and wide absorption band around 800 nm. For p polarization of the 5 at.% sample, the absorption coefficient at 799 nm and the linewidth were 21.9 cm-1 and 6.3 nm, respectively. The strong and broad absorption remits the requirements for the LD specification.
