摘要：

Yb-doped Y3Al5O12 (YAG) was matched in its lattice constant and thermal expansion to undoped YAG for the growth of zone-doped laser crystals in rod design (doped core, wrapped by the undoped mantle). Sc was used to expand the lattice. For the combination of (Y,Yb)(3)(Sc,Al)(5)O-12/YAG with 20 at% Yb on the dodecahedral sites, the difference of the lattice parameter between doped and undoped crystal regions could be reduced to 3.63 x 10(-3) Angstrom (= 3.02 x 10(-2)%). Crack-free intergrowth of the core and mantle material could be achieved. (C) 2002 Elsevier Science B.V. All rights reserved.
