BeAl_2O_4:T~(3+)crystals up to 120mm long and 20mm in diameter withoutbubbles and striations have been grown by doping the chrysoberyl bulks,whichwere previous
Mg:LiNbO_3 crystals were grown by buoyance balance controlled Czochralskitechneque from congruent melt(Li/Nb=48.60)doped with 0%,2%,5%,6%and 9% mole MgO.When t
