Abstract

Nondoped, Fe₂O₃ and Eu₂O₃-codoped near stoichiometric LiNbO₃(Eu:Fe:LiNbO₃) single crystals were grown by the top-seeded solution method. The solution with [Li]/[Nb] ratio of 1 contained K₂O component of 10.6mol%(7.0wt%). The ultraviolet-visible absorption spectra, infrared absorption spectra of the crystals were measured in order to analyze their structure. The photorefractive properties of stoichiometric LiNbO₃ crystals were investigated and compared with congruent LiNbO₃ crystal. Two-wave-coupling experiments shown that doped stoichiometric LiNbO₃ crystals exhibited much larger photorefractive gain and faster response speed than congruent ones.
