According to the customer request doped lithium niobate crystals (Cu, Fe, zinc, Mg, Er, Ce, Mn, Dy, Cs, Zr, Yb)

The lithium niobate crystal LiNbO_3:Fe:Mn was prepared by adding two trace elements, iron and cerium.

By synthesizing the photo-refractive, electro-optical and birefringent effects of lithium niobate crystals, the self-enhancement effect of double-doped LiNbO_3:Fe:Mn crystals in non-volatile holographic recording can effectively improve the photo-refractive sensitivity of the crystals to red light. Micro-optical components and optical systems designed and manufactured in a single crystal have the advantages of multi-function, integration and anti-interference, and are the research direction with important application prospects. The core technology is to fabricate high-efficiency non-volatile holographic gratings in a single lithium niobate crystal.

Dysprosium (Dy) ion doped lithium niobate crystal (Dy:LN) is mainly used in optical fiber communication, but also can be applied in the medical field, using the lithium niobate crystal excellent electro-optical and nonlinear optical properties, combining them with luminescence characteristics, can develop optical integrated devices with market prospects.

Cesium (Cs) ion doped lithium niobate crystal (Cs:LN) is a typical holosystem storage medium, which can produce self-reinforcing diffractive light under coherent visible laser radiation. The light damage resistance of lithium niobate crystals can also be improved after the addition of Zn and Sc elements.

The photo-damage resistance of zirconium-doped lithium niobate crystal (Zr:LN) is about six orders higher than that of the same composition lithium niobate crystal, and it is a better photo-refractive nonlinear photonics material than that of magnesium-doped lithium niobate crystal.

Ytterbium-doped (Yb) lithium niobate crystals (Yb:LN) have potential value in new wavelength self-doubling applications.
