Product Description
Fe Doped LiTaO3 Wafer for High-Density Holographic Storage
Lithium Tantalate (LiTaO3) is extensively utilized in optical applications including optical modulation, recording, and frequency conversion due to its electro-optic, acousto-optic, piezoelectric, thermal-optic, and photorefractive properties. With increasing demand for enhanced information storage capacity, Fe doped Lithium Tantalate (Fe:LiTaO3) provides an advanced solution for high-density and high-capacity holographic information storage.
