Abstract

Mg:Ru:Fe:LiNbO ₃ crystals with various doping concentration of MgO have been grown by Czochralski method. The type of charge carriers and photorefractive properties in Mg:Ru:Fe:LiNbO ₃ crystals were measured by two-wave coupling method using Kr ⁺ laser (476 nm) and He-Ne laser (633 nm) as light sources. We found that holes were the dominant charge carriers under blue light irradiation while electrons were the dominant charge carriers under red light irradiation. Mg ²⁺ ions behaved no longer as damage resistant, but promoter to the photorefractive properties at 476 nm wavelength. The photorefractive properties under blue light improved with the increase concentration of Mg ²⁺ ions. The enhancement mechanisms of the blue photorefractive were suggested. Experimental results definitely showed that Mg-doped two-centre Ru:Fe:LiNbO ₃ was a promising blue photorefraction material for holographic volume storage.
