Abstract
Thulium-doped gadolinium vanadate (Tm:GdVO4) single crystal has been successfully grown by a modified Czochralski (CZ) technique. Effective distribution coefficient of Tm was determined to be 0.74. Absorption characterization was performed in the 800 nm region and the maximum absorption peak was found at 799 nm for π polarization. Fluorescence spectra for tuning at the maximum absorption were obtained around 1.8-2.0μm region with 100 nm bandwidth. This suggests that a Tm:-GdVO4 crystal is expected as a new promising LD pumped solid-state laser in the 2μm region.
