Preparation method of thulium-holmium double-doped yttrium aluminum garnet laser transparent ceramic
The invention discloses a preparation method of thulium-holmium double-doped yttrium aluminum garnet laser transparent ceramic, and belongs to the technical field of optoelectronic materials. The method comprises three steps of Tm, Ho: Y3Al5O12 laser ceramic nano powder precursor preparation, green body forming and ceramic preparation, and a sol-gel method or a liquid phase co-precipitation methodis adopted to synthesize a high-purity, monodisperse, uniformly-doped and high-sintering Tm,Ho: Y3Al5O12 laser ceramic nano powder precursor. Through design and simulation, the structure-activity relationship of three rare earth ions of holmium Ho, thulium Tm and yttrium Y is regulated and controlled, and component control is achieved. By selecting an argon atmosphere, the valence state change and component segregation of aluminum are inhibited. The ceramic grown by the method has the characteristics of relatively easy preparation, low cost, better processability, isotropy, wide phase uniformity, high doping concentration, uniform distribution, no core caused by stress and impurities, good optical uniformity and the like, and is a laser ceramic material with a great development prospect.
