摘要: 本文研究了Nd3+、Ho3+、Dy3+和Ce3+稀土离子过量掺杂对TSAG陶瓷制备及相关性能的影响,结果表明:稀土离子过量掺杂对TSAG陶瓷的微观缺陷和透过率产生了一定的影响,晶粒表面存在非二次相的少量细小颗粒,从而导致陶瓷样品透过率下降。在相同测试波长下,稀土离子过量掺杂TSAG陶瓷的Verdet常数优于纯相TSAG陶瓷。此外,本文还探索了YAG/TSAG基双层复合结构陶瓷,成功制备了YAG/TSAG及YAG/2.0%Ce∶TSAG双层复合结构陶瓷,双层结构接触面形成了亚微米级厚度的过渡层,YAG/TSAG陶瓷在波长1 064 nm处的透过率达到71.0%,YAG/TSAG基复合陶瓷的成功制备,拓宽了TSAG材料在高功率激光器上的应用前景。

Abstract: In this paper, the effects of over-doping of Nd3+, Ho3+, Dy3+ and Ce3+ rare earth ions on the preparation and related properties of TSAG ceramics were investigated, and the results show that over-doping of rare earth ions has a certain effect on the micro-defects and transmittance of TSAG ceramics. The existence of a small number of fine particles which are not in the secondary phase on the grain surface, led to the decrease of the transmittance of the ceramic samples. The Verdet constant of rare earth ion over-doped TSAG ceramics is better than that of pure phase TSAG ceramics at the same test wavelength. In addition, YAG/TSAG-based bilayer composite structural ceramics were explored. The YAG/TSAG and YAG/2.0%Ce∶TSAG bilayer composite structural ceramics were successfully prepared, with sub-micron thickness transition layer formed on the contact surface, and the transmittance of the YAG/TSAG ceramics at 1 064 nm reaches 71.0%. The successful preparation of YAG/TSAG-based composite ceramics broadens the application prospects of TSAG materials in high-power lasers.
