Zinc doped Lithium Niobate (Zn:LiNbO3) is a type of optoacoustic (OA) crystal that can be used for acousto-optic (AO) applications such as deflection, modulation, and beam steering. The addition of Zinc ions to LiNbO3 crystal lattice introduces nonlinearity in the crystal, allowing for efficient interaction between optical and acoustic waves. This makes Zn:LiNbO3 a useful material for various applications in photonics, such as telecommunications, spectroscopy, laser systems, and sensing. The high optical transparency and strong electro-optic effect of Zn:LiNbO3 makes it an attractive material for AO applications.
