Notes:
Commercial Y2O3 powders were subjected to high energy ball milling in a planetaryball mill using high purity alumina balls and vial. The refined Y2O3 power ,withcommercial high-purity Al2O3, Cr2O3 and Yb2O3 powders, were used as rawmaterials. Transparent ytterbium and chromium codoped yttrium aluminum garnet(Yb,Cr:YAG) ceramics were fabricated by a solid-state reaction method. TheYb,Cr:YAG ceramics exhibit a pore free structure and the average grain size is about10 micron. The strong absorptions at 940 and 968 nm of Yb3+ are suitable for InGaAsdiode laser pumping, and there is an absorption band at 1030 nm, which is suitable forpassive Q-switch laser output at 1030 nm. Transparent Yb,Cr:YAG ceramics may be apotential material for compact, efficient, high-stability diode-laser-pumped passiveQ-switched solid-state lasers
