摘　　要：本文首次采用提拉法生长出了四方晶系白钨矿结构的Yb :NaY(WO4 ) 2 晶体 ,通过TG DTA分析得到晶体的熔点为 1 2 1 1℃ ,测试了该晶体的红外光谱、拉曼光谱和吸收光谱。结果表明 ,该晶体在 84 8nm、96 8nm附近有较强、较宽的吸收峰 ,适合于LD泵浦。Tetragonal scheelite-like Yb:NaY(WO_4)_2 single crystals have been grown by Czochralski method for the first time. Differential thermal analysis experiments show that melting point of the crystal is at 1211℃. The Infrared spectra、Raman spectra and absorption spectra of Yb 3+ doped NaY(WO_4)_2 crystal have been measured at room temperature. We found that absorb peas of the crystals at 848nm、968nm were better and wider, and the crystal were propitious to LD pump.
