Blue single crystals of magnesium aluminium spinel doped with nickel have been pulled from the melt, by the Czochralski
technique. The transmission spectrumof doped samples show three broad absorption bands. Accordingto the absorption map and
the chemicalanalysisof these crystals,the effectivesegregationcoefficientof Ni 2+ in Mgml204 seems to be roughly 1.At T = 80 K,
the expectedtuning range of the stimulatedemissionlies from 1.2 to 1.4 gm.

with transition metals are the most promising The raw materials used were:
materials for infrared tunable lasers. Magnesium - Exal a: A1203 (Rubis Synthrtique des Alpes);
oxide doped with nickel seems to be the best, but, - Grade 1 MgO (Johnson-Matthey Chem. Ltd.)
unfortunately, single crystals of magnesia are not dried first at 1000°C;
