本文报道了采用流延和真空烧结工艺制造光学级 YAG/Re:YAG/YAG（Re=Yb 或 Nd）复合激光陶瓷。研究了分散剂含量对浆料流变行为、微观结构、光学和激光性能的影响。实验结果表明，当输出耦合器的透过率(Toc)为2.3%时，YAG/Yb:YAG/YAG可产生1030nm的激光输出，阈值吸收泵浦功率为4.33W，斜率效率约为12%。对于YAG/Nd:YAG/YAG陶瓷，获得了1064nm激光输出，斜率效率从30%提高到38%，而Tc从2.3%改变到10%。
This paper reports the use of tape casting and vacuum sintering process for the fabrication of optical grade YAG/Re:YAG/YAG (Re=Yb or Nd) composite laser ceramic. The influence of dispersant content on the rheological behavior of the slurry, the microstructure, the optical and laser performances, were studied. The experimental results showed that laser output at 1030nm was generated for YAG/Yb:YAG/YAG with threshold absorbed pump power of 4.33W and slope efficiency of about 12% when the transmission of output coupler (Toc) was 2.3%. For YAG/Nd:YAG/YAG ceramic, 1064nm laser output was obtained, and the slope efficiency increased from 30% to 38% while Tocchanged from 2.3% to 10%.
