popup.description1
Studying the influence of the sintering temperature and structural defects caused by the substitution of atomic positions in the YAG structure with Si4+ and Mg2+ heterovalent impurities on the formation of the structural phase state, diffusion mass transfer processes, and optical properties of YAG:Sm3+ transparent ceramics. Production of large-scale experimental samples of YAG:Sm3+ optical ceramics for ceramic laser environments of complex architecture.
popup.description2
The results of the project show that both the selection of initial components and the adjustment of planetary grinding modes can significantly influence the microstructure and optical properties of the resulting ceramics. The optimal grade of the initial Al2O3 powder was selected, and the intensity of planetary grinding of powder mixtures Y2O3+Al2O3+Sm2O3 was optimized, which made it possible to obtain experimental samples of optical ceramics 3at.% YAG:Sm3+ with a thickness of up to 4 mm with an optical loss level of 4.9×10-2 cm-1 at a wavelength of 808 nm.
