摘要：

To　increase　concentration　of　Yb3+-ions　in　BaWO4　crystals,　co-doped　K+-ions　method　were　adopted.　Absorption　coefficient　of　K+(x　(K+)　=　0.01),　Yb3+　(x　(Yb3+)　=　0.02):BaWO4　crystals　is　α　=　0.494　cm-1　at　977　nm.　Fluorescence　spectra　of　Yb3+-ions　from　960　nm　to　1020　nm,　corresponding　to　transition　2F5/2　→　2F7/2　was　investigated.　Emission　cross　section　at　1005　nm　is　6.286　×　10-20cm2,　livetime　is　0.4　ms.　The　experimental　result　shows　that　K+,　Yb3+:BaWO4　is　a　potential　laser　crystal.
