摘　　要：文章主要针对基于放电等离子体烧结方法制备的透明Nd:Lu_2O_3陶瓷激光性能展开实验研究。研究结果显示,退火后的Nd:Lu_2O_3陶瓷样品激光性能远优于退火前的样品:当采用直线腔测试方法时,退火后样品获得了最高功率为880 mW,最大斜效率为40%的输出;当采用V型腔测试方法时,退火后样品获得了最高为1.25 W,最大斜效率为38%的输出,输出光谱包含了两条位于1 076.7 nm和1 080.8 nm的谱线,但功率的进一步提高受到严重的热透镜效应限制。实验结果表明,通过放电等离子体烧结方法可以制备出高光学质量的Nd:Lu_2O_3陶瓷样品。High efficient laser operation based on the SPSed （spark plasma sintering） Nd：Lu203 ceramic was investigated in this paper. Laser performance of Nd：Lu203 samples before and after anneal were tested respectively, and results show that the samples after anneal have much better optical quality. When a linear cavity was used, the annealed Nd：Lu203 ceramic sample can output maximum power of 880 mW with a corresponding slope efficiency of 40%. When a V-shape cavity was used, annealed Nd：Lu203 ceramic sample can output maximum power of 1.25 W with a corresponding slope efficiency of 38%. The laser spectral lines at 1 076.7 nm and 1 080.8 nm oscillated simultaneously, but the thermal lensing effect limited the increase of output power of the Nd：Lu203 ceramic laser. Experimental results showed that the high optical quality Nd：Lu203 ceramic can be fabricated by the spark plasma sintering method.
