Doping possibilities of Al2O3 and YAG crystals grown from the melt alternatively doped with alkali earth, silicon, iron group or molybdenum ions under 98% Ar – 2% H2 or 98% He – 2% H2 protective atmosphere are described. Alkali earth and particularly Si ions evaporate slowly from the melt. Reduction of iron group ions was observed. Mo may enter YAG phase using a wet protective atmosphere. Al2O3 phase contains Mo ions if grown from the electrolyzed melt.
