采用提拉法生长出了纯的和Nd3+、Tm3+、Dy3+、Ho3+、Pr3+离子掺杂的大尺寸优质的NaLa(WO4)2晶体.TG/DTA实验表明NaLa(WO4)2晶体在1251℃同成分熔化,热膨胀实验结果显示该晶体沿(100)和(001)方向的热膨胀系数分别为1.23×10-5K-1和2.49×10-5K-1.在室温下测量了该晶体的红外和拉曼光谱,对晶体的振动性质进行了研究.对稀土离子掺杂的NaLa(WO4)2晶体进行了光谱性质的研究.N3+:NaLa(WO4)2和Tm3+:NaLa(WO4)2晶体800 nm附近的吸收峰半高宽和吸收截面较大,有利于用LD泵浦.采用小型的氙灯泵浦,研究了Nd3+:NaLa(WO4)2晶体的激光特性.当氙灯输入能量为1.28 J时,获得14.77mJ的激光输出能量,光光转换效率为1.15%.
