In this report, the photorefractive properties in barium titanate() crystal are associated with the concentration variation. Not only the change of the shallow concentration can be estimated through the light-induced absoption, but the relation between oxygen partial pressure also. A correlation between measurement of photoconductivity and light-induced absorption yields the concentration variation is a function of oxygen partial pressure. Otherwise, the wavelength dependent photorefractive properties of the are investigated and discussed.
