Paper Abstract

Composite YAG/2.0at%Nd:YAG transparent ceramic was fabricated by solid-state reactive sintering a mixture of commercial α-Al2O3, Y2O3, and Nd2O3 powders with tetraethoxysilane (TEOS) and MgO as sintering additives. A fully dense YAG/2.0at%Nd:YAG ceramic with an average grain size of ~20μm was obtained by vacuum sintering at 1750°C for 50h. There are almost no pores or second phases present at grain boundaries or inner grains. The in-line transmittance reached 83.6% at the lasing wavelength of 1064nm and 82.0% at 400nm. The porosity of the sample was at the level of several vol ppm. The composite YAG/2.0at%Nd:YAG transparent ceramics are promising to generate high-energy laser.
