Radiation-resistant composite transparent ceramic for sunlight pumped laser and preparation method of radiation-resistant composite transparent ceramic
The invention discloses an anti-radiation composite transparent ceramic for a sunlight pump laser and a preparation method of the anti-radiation composite transparent ceramic, the surface of an xRe, yNd: YAG transparent ceramic rod is sequentially compounded with a zSm: YAG/Al2O3 porous nano ceramic layer from inside to outside, and vacuum sintering is carried out, x is more than or equal to 0.01, y is more than or equal to 0.005 and less than or equal to 0.06, z is more than or equal to 0.001 and less than or equal to 0.02, Re ions are Ce < 3 + > and/or Cr < 3 + >, the thickness of a single porous nano ceramic layer is 10-30 microns, and the diameter of a nano pore channel is 10-50 nm. The Sm ion edge-covering material has the advantages that defects such as interstitial atoms and vacancies generated by irradiation are absorbed by porous nano-layer channels, and gas atoms can be released out of the material, so that the defect concentration in the material body is greatly reduced, the irradiation resistance of the material is greatly improved, and meanwhile, the Sm ion edge-covering material can effectively absorb electrons in the radiation, so that the radiation resistance of the material is improved. And parasitic oscillation and amplified spontaneous emission generated in the excitation process are inhibited. And the prepared composite ceramic material can effectively dissipate heat in time, and the heat effect problem in the ceramic service process is relieved.
