Study On The Preparation, Characterization And Properties Of Yb: YGG Laser Ceramic Powder

As a new hot research of solid-state laser working material, the technology of laser ceramic material is the key and foundation for preparing high property transparent laser ceramic materials. In this dissertation, Yb:YGG laser ceramic material were synthesized by sol-gel combustion method and co-precipitation method respectively for the first time. The preparation technology of Yb:YGG ceramic material were studied. And the samples were characterized via XRD, TG-DTA, SEM, IR spectrum and fluorescence spectra.The structure, morphology and fluorescence property of Yb:YGG ceramic material synthesized by sol-gel combustion method were characterized. XRD shows that the Yb:YGG are armorphous phase when it was calcined at 700℃. Pure YGG can be obtained at 800℃, which is consistent with TG-DTA. SEM shows that the particle size is about 80nm and no agglomeration. The result of fluorescence property shows that there is better fluorescence emission property around 1030nm.The structure, morphology and fluorescence property of Yb:YGG ceramic material synthesized by co-precipitation method were characterized. XRD shows that the Yb:YGG are armorphous phase when it was calcined at 800℃. Pure YGG can be obtained at 900℃. which is consistent with TG-DTA. SEM shows that the particle size is about 100nm and a little agglomeration. The result of fluorescence property shows that there is better fluorescence emission property around 1030nm.Contrast various performance of Yb:YGG ceramic material prepared by sol-gel combustion method and co-precipitation method, it was concluded that sol-gel combustion method was more suitable for the preparation of Yb:YGG laser ceramic material than co-precipitation method.
