Rodlike concentric circle structure garnet-based laser transparent ceramic and preparation method thereof
According to the preparation method of the garnet-based laser transparent ceramic with the rod-shaped concentric circle structure, components of a prepared ceramic inner core and a cladding meet the following formula: (M1-xRex3) 3 (Al1-yCry) 5O12, in the formula, x is more than or equal to 0 and less than or equal to 0.5, y is more than or equal to 0 and less than or equal to 0.02, M is one of Y, Lu and Gd, and Re is one of Ce, Nd, Ho, Yb, Sm, Tm, Pr and Er. The garnet-based transparent ceramic with the rodlike concentric circle structure is prepared by coating a ceramic biscuit formed by cold isostatic pressing with a ceramic diaphragm prepared by tape casting. The method is simple and easy to implement and does not need to design a complex structure mold; the radial and axial lengths of the biscuit can be self-defined, and the die does not need to be frequently replaced. The prepared transparent ceramic is excellent in optical performance, the linear transmittance of the ceramic at 1064nm is 81.5-84.6%, and the application requirements of solid lasers and solid lighting can be completely met.
