摘要：

A Dy3+-doped NaBi(WO4)(2) crystal was successfully grown by the Czochralski method. Spectroscopic properties of the crystal at room temperature were measured and analyzed. Peak absorption cross-sections of the H-6(15/2) -> I-4(15/2) transition for the crystal are 1.4 x 10(-21) and 2.3 x 10(-21) cm(2) with full widths at half maximum of 7.5 and 6.6 nm for sigma and pi polarizations, respectively, and at 454 nm for both polarizations. Meanwhile, the crystal exhibits a strong yellow emission at 574 nm corresponding to the F-4(9/2) -> H-6(13/2) transition with peak cross-sections of 0.97 x 10(-20) and 1.27 x 10(-20) cm(2) for sigma and pi polarizations, respectively. The fluorescence lifetime and quantum efficiency of the F-4(9/2) multiplet were estimated to be 179 mu s and 80%, respectively. It has been found that the cross relaxation plays an important role in the relaxation of the F-4(9/2) multiplet. The results show that the Dy3+:NaBi(WO4)(2) crystal may be a promising gain medium of the 574 nm yellow laser pumped by a blue laser diode at 454 nm.
