摘要/Abstract

摘要： 利用改进的提拉法生长了一种新型YVO₄-Nd∶YVO₄ 复合晶体,在晶体中部实现了Nd³⁺的0.10%~0.25%(原子数分数)浓度梯度掺杂。晶体中, Nd³⁺掺杂区的弱吸收系数较未掺杂区大,表现出界面吸收现象。观测了复合晶体对泵浦光的吸收和温度分布,发现晶体沿轴向的泵浦吸收相对均匀,温度梯度相对较小。未镀膜的复合晶体样品在1 064 nm波段显示了良好的连续激光性能,光-光转换效率为37.0%,斜效率为40.9%。

Abstract: A new YVO₄-Nd∶YVO₄ composite crystal was grown by a modified Cz method, a 0.10%~0.25%(atomic ratio) concentration gradient doping of Nd³⁺ in the middle part of the crystal was achieved. In the crystal, the weak absorption coefficient of the Nd³⁺ doped region is larger than that of the un-doped region, indicating the interface absorption phenomenon. By observing the absorption of the pump light by the composite crystal and temperature distribution in the crystal, it is found that the pumping absorption of the crystal along the axial direction is relatively uniform, and the temperature gradient in the crystal is relatively small. The uncoated composite crystal samples achieve well performance of CW laser at 1 064 nm, with a light-to-light conversion efficiency of 37.0% and a slope efficiency of 40.9%.

Key words: vanadate crystal, composite crystal, laser crystal, concentration gradient, weak absorption, temperature gradient, laser performance
