Abstract
Dy:GdVO_4 single crystals were successfully grown by the floating zone method. All the grown crystals had no macroscopic defects such as inclusions and low-angle grain boundaries. An intensive fluorescence peak was observed at 573nm, which is assigned to the radiation from ^4F_<9/2> to ^6H_<13/2>. The excitation spectrum for the 573nm emission had a peak around 450nm. These results indicate Dy:GdVO_4 single crystals can be one of the candidates for LD-pumped yellow-laser materials.
