| 摘 要： | 以K2W2O7为助熔剂,Tm3+掺杂摩尔分数为8%,采用顶部籽晶提拉法生长出了单斜晶系的铥掺杂钨酸镱钾Tm3+:KYb(WO4)2,Tm:KYbW]晶体.测试了晶体的红外光谱和Raman光谱,并对出现的峰值进行了振动归属.测量了晶体的吸收光谱和荧光光谱,计算了相应的光谱参数.吸收光谱显示:Yb3+在945,958nm处吸收峰最强,半峰宽为91 nm.荧光光谱表明:Tm:KYbW晶体在1 735nnl和1 759nm附近有较强的发射峰,主峰1 759nm处的发射线宽达146nm,因此,Tm:KYbW晶体可作为可调谐激光增益介质.晶体的上转换荧光谱表明:在481 nm和646nm处分别得到了上转换蓝光和红光,并分析了相应的上转换机制.
