摘　　要：采用燃烧法制备了Nd:YSAG粉体,经过成型、素烧,最终在氢气气氛中烧结制备了Nd:YSAG透明陶瓷.测试结果表明,Nd:YSAG透明陶瓷具有荧光谱线较宽,荧光寿命较长的特点.激光实验得到的激光输出,斜率效率为23.6%,输出功率为0.36W,输出激光的谱线分布较宽.Nd：YSAG powders was prepared by using combustion method. After molding, calcining the Nd：YSAG green compact at 1750- 1850℃ in H2 atmosphere for 4-10h, the transparent Nd：YSAG ceramics were obtained. The optical properties of Nd：YSAG transparent ceramics were measured. The emission band of transparent Nd：YSAG ceramics is broadened and the fluorescence lifetime is prolonged as compared to Nd：YAG ceramics. Using LD as pumping source, and transparent Nd：YSAG ceramics as laser gain media, laser output is achieved. The maximum laser power is 0.36W and the slope efficient is 23.6%, the spectrum band of output laser is relatively broad.
