Abstract
In accordance with the present embodiment, a method for making an optical ceramic comprises depositing a plurality of thin layers of powder. The powder comprises a first optical material powder having a first dopant level, and a second optical material powder. The first and second optical material powders are deposited for each layer based on the first dopant level and according to data associated with a three-dimensional (3D) compositional profile design of an optical ceramic. The method further comprises binding the first and second optical material powders of each thin layer to each other and each thin layer with an adjacent layer such that a green state optical ceramic is produced based on the 3D compositional profile design. The method further comprises densifying the green state optical ceramic to obtain the optical ceramic.
