摘要

The reasearch main objective is to obtain ceramic laser materials based on pure YAG (Y3Al5O12) and Nd doped YAG (Y-3-xNdxAl(5)O(12), with x = 0.5 and 1.0 at. %), by conventional solid state reaction method. Stoichiometric compositions of Y3Al5O12 (YAG), Y2.985Nd0.015Al5O12 (0.5 at.% Nd: YAG) and Y2.97Nd0.03Al5O12 (1.0 at.% Nd: YAG) were prepared using high purity Y2O3 (99.999%), Al2O3 (99.999%) and Nd2O3 (99.999%) nanopowders. Green bodies were sintered at 1750 degrees C for 16 h under vacuum (1.0 x 10(-3) Pa) and then annealed at 1450 degrees C for 10 h in the air.
