摘要/Abstract

摘要： 本文采用提拉法首次生长了晶体尺寸为ϕ50 mm×100 mm的Nd∶TSAG磁光晶体,对其结构、光谱、磁光及热学性能进行了研究,并对振子强度和线强、强度参数Ω_t、⁴F_3/2→⁴I_J能级间的跃迁概率、能级辐射寿命、荧光分支比等光谱参数进行了计算。对Nd∶TSAG多晶样品掺杂浓度进行了优化,Nd³⁺的最佳掺杂浓度(原子数分数)为1%。晶体及粉末X射线衍射分析结果表明,晶体为纯相且结晶质量较好,Nd³⁺在TSAG晶体中的分凝系数为0.64。Nd∶TSAG晶体在可见和近红外波段,除了Tb³⁺和Nd³⁺的特征吸收,透过率达到80%以上。在808 nm激发下,Nd∶TSAG的最强荧光峰在1 070 nm附近。Nd∶TSAG晶体在473、532、632.8、1 064 nm波长处的折射率分别为1.925 9、1.915 3、1.903 8和1.885 2,拟合了四参数Sellmeier折射率方程。采用消光法测试了Nd∶TSAG晶体在405、532、635、1 064 nm波长处的Verdet常数分别为599.8、202.8、152.3、46.8 rad·m^-1·T^-1。室温下,Nd∶TSAG晶体的热导率为3.95 W/(m·K)。研究结果表明,Nd∶TSAG是优异的磁光晶体,也是潜在的优异激光晶体,有望同时实现磁光和激光的功能。

Abstract: Nd∶TSAG magneto-optical crystal with the size of ϕ50 mm×100 mm were grown by Czochralski method for the first time. The structure, spectra, magneto-optical, and thermal properties of the crystal were studied in detail. Spectral parameters, such as oscillator strength, line strength, intensity parameter Ω_t, transition probability between ⁴F_3/2→⁴I_J energy levels, radiation lifetime, and fluorescence branching ratio were calculated. The doping concentration of Nd∶TSAG polycrystalline samples was optimized, and the best doping concentration of Nd³⁺(atomic fraction) is 1%. The results of X-ray diffraction analysis of crystal and powder show that the crystal has a pure phase and good crystal quality. The separation coefficient of Nd³⁺ in TSAG crystal is 0.64. In the visible and near infrared bands, the transmittance of Nd∶TSAG crystals is over 80%, except for the characteristic absorption of Tb³⁺and Nd³⁺. With 808 nm excitation, the strongest fluorescence peak of Nd∶TSAG is around 1 070 nm. The refractive indices of Nd∶TSAG crystals at 473, 532, 632.8, and 1 064 nm are 1.925 9, 1.915 3, 1.903 8, and 1.885 2, respectively. The four-parameter Sellmeier refractive index equation is fitted. The Verdet constants of Nd∶TSAG measured by extinction method at 405, 532, 635, and 1 064 nm are 599.8, 202.8, 152.3, and 46.8 rad·m^-1·T^-1, respectively, which are higher than that of TGG crystals. At room temperature, the thermal conductivity of Nd∶TSAG crystals is 3.95 W/(m·K). The results show that Nd∶TSAG is an excellent magneto-optical crystal and a potential excellent laser crystal. Meanwhile, it is promising to realize the synergistic effect of magneto-optic and laser.
