摘要
以国产商业纳米粉为原料,采用传统固相法制备直线透过率大于80%的高光学质量的氧化镧钇和掺钕氧化镧钇透明陶瓷。氧化镧钇透明陶瓷透光范围在0.3～8.5μm,可用于高温红外窗口;掺钕氧化镧钇透明陶瓷具有掺钕氧化钇透明陶瓷几乎一致的激光光谱性能,但其吸收带宽更大,在激光泵浦源806nm波段,吸收带宽达到7nm,有利于激光器件的小型化。Nd0.03Y1.77La0.2O3透明陶瓷实现连续激光输出,在1080nm波长最大激光输出功率为63mW。
High optical quality undoped and Nd-doped yttrium lanthanum oxide transparent ceramics with highest in-line transmit-tance over 80% were fabricated with home commercial nanopowders by the conventional solid state reaction synthesis processing. The transmission range of yttrium lanthanum oxide transparent ceramics is 0.3–8.5 μm,so it can be used as high temperature infrared window material. Nd-doped yttrium lanthanum oxide transparent ceramics has the similar laser spectroscopic properties as Nd-doped yttria transparent ceramics,but with broader absorption band. The absorption band width reaches 7 nm at the laser diode pumping wavelength of 806 nm,which is beneficial to the miniature of the laser device. A diode-pumped new Nd0.03Y1.8La0.2O3 ceramic laser was obtained and the highest continuous wave laser output is 63 mW at 1 080 nm.
