In:Fe:LiNbO3 crystals have been grown by doping indium ions in Fe:LiNbO3 crystals. Experimental demonstrations are performed by recording in Fe:LiNbO3 and InFe:LiNbO3 crystals with a focused near infrared laser beam of 1064 nm wavelength. The near infrared photorefractive properties of Fe:LiNbO3 and InFe:LiNbO3 crystals are comparatively studied by the digital observation device. The experimental research results show that the photorefractive response and the photorefractive resistance ability are improved highly, and the saturation refractive index change Δn decreases in the InFe:LiNbO3 crystal. The enhancement mechanism of photorefractive properties is preliminary discussed in InFe:LiNbO3 crystals. The modification of indium ions substitutes the sites of light sensitive centers in the InFe:LiNbO3 crystal, and the number of light sensitive centers is decreased rapidly. It also induces the improvement of photoconductive property and cut the response time.
