The BaWO4:Tm3+ single crystals of optical quality have been grown by the Czochralski technique. The lattice parameters of crystals with different doping concentrations were determined by XRD. The absorption spectra were measured at room temperature. And the optical parameters, such as transition line intensity, oscillator strength and absorption section were calculated by using Juud-Ofelt theory. The three intensity parameters were fitted to be Ω2=404×10-20cm2 Ω4=0509×10-20cm2Ω6=0134×10-20cm2 respectively. The lifetime, branching ratio and integrated stimulated-emission cross section were obtained. Ultra-visible fluorescence was measured and analyzed. The red up-conversion luminescence with wavelengths 689 nm and 704 nm corresponding to the transition from 3F3 to 3H6 was observed under Ti-sapphire laser and LD laser, respectively.
