| 英文摘要 | this paper demonstrates that we can further eliminate the remaining micro pores by hot isostatic press (hip) approach. the porosity of nd:luag laser ceramics sharply declined from 7 x 10(-6) to 5.60 x 10(-7) after additional hip. annealing is one of the key steps to optimize the quality of vacuum sintered ceramics, such as make the transmittance rise from 79.98% to 81.02% at 1200nm. however, the trend is in the opposite direction for the hiped nd:luag:fallen from 82.65% to 25.50% at 1200nm. the microstructure of nd:luag studied by microscope, sem and tem shows that a large number of pores and a few second phases like lu2sio5 appeared along grain boundaries in post-annealed hiped nd:luag. the gas composition was confirmed as argon by gcms analysis. by further optimizing the annealing process of hiped ceramics we found that vacuum annealed at 1600 degrees c for 10h and oxygen re-annealed at 1200 degrees c for 30h can reduce pores and make the ceramic quality better, the transmittance can reach 83.05% at 1200nm, and the porosity dropped to 3.2 x 10(-7).
