在室温下测量和分析Er~(3+)/Yb~(3+): KY(WO_4)_2晶体三个折射率主轴方向上的吸收光谱和荧光光谱,其吸收光谱和荧光光谱谱带强度明显呈现各向异性;用修正的Judd-Ofelt理论计算Er~(3+)/Yb~(3+): KY(WO_4)_2晶体中Er~(3+)在三个折射率主轴方向上的强度参量Ω_t (t=2,4,6)和各吸收谱带的电偶极跃迁振子强度,同时计算了Yb~(3+)在三个轴向上980 nm波长处的积分吸收截面.结果表明:Er~(3+)/Yb~(3+): KY(WO_4)_2晶体吸收光谱和荧光光谱存在各向异性,N_p轴为Er~(3+)/Yb~(3+): KY(WO_4)_2激光晶体的最佳泵浦轴向.
