Growth of heavily doped LiNbO3〈Zn〉 crystals

We have studied conditions for the growth of LiNbO 3 〈Zn〉 crystals in the composition range ≃4.0–8.91 mol % ZnO. It has been shown that, in the composition range ≃4–6.8 mol % ZnO in the melt, compositionally and optically homogeneous LiNbO 3 〈Zn〉 crystals can be grown. Above 6.8 mol % ZnO, imperfect...

Description
Summary:We have studied conditions for the growth of LiNbO 3 〈Zn〉 crystals in the composition range ≃4.0–8.91 mol % ZnO. It has been shown that, in the composition range ≃4–6.8 mol % ZnO in the melt, compositionally and optically homogeneous LiNbO 3 〈Zn〉 crystals can be grown. Above 6.8 mol % ZnO, imperfect crystals consisting of two distinct phases grow. We have accurately determined threshold impurity concentrations corresponding to significant changes in LiNbO 3 〈Zn〉 crystallization conditions.
