In this paper, synthesis of Yb:GGG nanopowder were carried out by coprecipitation method, respectively. The synthetized powder were used for transparent ceramic sintering, which obtained preferably Yb:GGG transparent laser ceramics. The particle size of the prepared nanopowder is small and uniform, the granularity is approximate 80nm. The nanopower has high sintering activity and the optimal sintering temperature and holding time are 900℃ and 4 hours, respectively. The nanopowder were molded and presintered, then Yb:GGG transparent ceramics were pre-pared by vacuum sintering method. The structure, morphology and optical properties of transparent ceramics were char-acterized and tested by using XRD,SEM, fluorescence spectra and transmittance spectra.
