摘　　要：采用溶胶凝胶法制备Tm,Ho:YAG纳米粉体以及透明陶瓷,并对纳米粉体和透明陶瓷进行了分析。结果表明:在经过了900℃煅烧后,纳米粉体已经形成了YAG晶相,在785~398 cm^-1这一范围的特征振动峰是YAG特有的晶格所引起的振动。Tm,Ho:YAG透明陶瓷结构致密。在1.97~2.03μm的测试波长范围内,透过率大于84%。经过780 nm的泵浦光源激发后,能够稳定的发出波长为2.03μm的激光。Tm-and Ho-codoped yttrium aluminum garnet(YAG) nanopowders were prepared by the sol-gel method, and a transparent ceramic was prepared from the obtained powders. X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and fluorescence spectroscopy were used to analyze the synthesized nanopowders and transparent ceramic. The results show that after calcination at 900 ℃, the nanopowders formed the crystal phase of YAG, and the characteristic peaks in the range of 785 to 398 cm^-1 correspond to vibrations of the unique lattice of YAG. After preparing the transparent ceramic, a compact structure was achieved. In the range of 1.97-2.03 μm, the transmittance was greater than 84%. After excitation by a 780 nm pumped light source, stable laser emission at a wavelength of 2.03 μm was produced.
