Rare earth (RE) doped polycrystalline Al2O3 ceramics have attracted increasing research interest in the past decade for lasing and lighting applications because of their outstanding thermal conductivity and fracture strength enabling power scaling. However, the optically anisotropic nature of Al2O3...
