Product Description
The LiNbO 3: Fe: Mn double doped LiNbO 3: Fe: Mn was prepared by doping Fe and CE into LiNbO 3 crystal.
By using the photorefractive, electro-optic and birefringence effects of LiNbO 3 crystal, the self enhancement effect in the nonvolatile holographic recording of double doped LiNbO 3: Fe: Mn crystal can effectively improve the photorefractive sensitivity of the crystal to red light. The micro optical components and optical systems designed and fabricated in a single crystal have many advantages, such as multi-function, integration and anti-interference, which are the research directions with important application prospects. Among them, the core technology is to fabricate high-efficiency nonvolatile holographic grating in a single lithium Niobate crystal.
