Paper 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.
