Based on the band transport model, the two-center nonvolatile holographic recording in (Ce,Cu)∶LiNbO3 has been theoretically investigated and optimized. Microphysical parameters of (Ce,Cu)∶LiNbO3 crystal are obtained and used to rigorously solve two-center band transport equations by numerical algorithm. The effects of recording and sensitizing intensities, dopant concentration of Ce and Cu, and microphysical parameters on recording performance of two-center holographic recording have been analyzed. And the characteristic of two-center recording in (Ce,Cu)∶LiNbO3 crystal has been found, that the deep center Cu plays a key role in the recording process and a strong space-charge field has been built in Cu traps, so a high diffraction efficiency and fixing efficiency can be achieved.

The Dy3+ doped congruent LiNbO3 crystal is mainly used in optical fiber communication, and also can be used in the medical field. Using LiNbO3 crystal’s excellent electro-optic and nonlinear optical properties and combining them can be developed extremely has the market prospect of integrated optical devices.

The Cs+ doped congruent LiNbO3 crystal is a typical holographic storage medium, in a coherent beam visible under the laser radiation, Cs:LiNbO3 could produce self-reinforced diffraction of light.

The Zn2+/Sc3+ co-doped congruent LiNbO3 crystal can obviously change the optical damage resistance.

The Zr4+ doped congruent LiNbO3 crystal could increased the laser damage threshold as much as 106 times over that of undoped LiNbO3,and also more excellent resistance to photorefractive than that of Mg-doped.

The Yb3+ doped congruent LiNbO3 crystal has the potential application value in the new spectra self-frequency-doubled laser.
