Abstract
Neodymium-doped yttrium-aluminum garnet (Nd:YAG) ceramics that contained 0.025, 0.05 and 0.10 at% Nd2O3 additives and exhibited nearly the same optical properties as those of a single crystal were fabricated by means of the sol-gel technique and hot press sintering method. Transparent YAG and Nd:YAG ceramics are fabricated either by high-temperature vacuum sintering or post-hot isostatic pressing but not hot pressing. 0.5 mass% TEOS was used as a sintering aid. A nearly pore-free microstructure with an average grain size of 5 – 10 μm was obtained by sintering at 1700 °C. The optical transmittance of the samples was 98 % in the 532 nm wavelength.
