报道了用微波辅助均相沉淀法(MAHP)制备透明的Nd:Y3Al5O12陶瓷的激光输出。在温度为25℃、湿度为30%~50%的条件下,对经过6d老化处理的前驱体颗粒进行热处理,得到了平均粒径小于100 nm的纯相、均匀的纳米粉末,并在1730℃下真空烧结10h,获得了斜率效率为5.1%的激光输出(305 MW)。我们的结果表明,MAHP方法有可能用于激光陶瓷产品的制备。
We report the laser output of transparent Nd:YAG (Nd:Y3Al5O12) ceramics fabricated from Nd:YAG precursors through the microwave-assisted homogenous precipitation (MAHP) method. Pure phase and uniform Nd:YAG nano-powders with average sizes less than 100 nm were obtained by heating treatment of the Nd:YAG precursor particles aged for 6 d in vessel with humidity of 30%–50% at 25°C. Transparent Nd:YAG ceramic pellets were obtained by vacuum sintering at 1730°C for 10 h. Laser output (305 mW) with a slope efficiency of 5.1% was realized through an end-pumped configuration. Our results indicate that the MAHP method could potentially be used for the fabrication of laser ceramic products.
