Abstract

•Hf: Nd: LiNbO3 crystals with various [Li]/[Nb] ratios ([Li]/[Nb] = 0.94, 1.05, 1.20, 1.38) were grown.•The effective distribution coefficient of Hf4+ is reduced and that of Nd3+ is increased with the increase of [Li]/[Nb] ratio in the melts.•Hf: Nd: LiNbO3 crystals with 1.05 [Li]/[Nb] ratios was the stoichiometric.•The exposure energy of Hf: Nd: LiNbO3 crystal with the [Li]/[Nb] ratios of 1.38 is 687.35 J/cm2.
