Product Description
Optical Czochralski Lithium Niobate (LiNbO3, LN) Crystals for Holographic Recording
LiNbO3 crystals are the most commonly used material for pockel cells, Q-switches and phase modulators, waveguide substrates, surface acoustic wave (SAW) wafers, etc.
Lithium niobate (LiNbO3, LN) crystals doped with iron (Fe:LiNbO3) is an attractive photorefractive material, due to high photorefractive sensitivity, high electro-optic coefficients and diffraction efficiency, chemomechanical properties. Fe:LiNbO3 crystals are grown by Czochralsky method and available in large size. Wide range of available dopants and levels enable to adjust material properties for particular applications. What is more, Fe:LiNbO3 crystals feature ease to handle, low cost, therefore suitable for volume production.
Main features
High electro-optic coefficient (r41=5 pm/V)
High phase conjugation efficiency
Available in large size elements or wafers up to 3"
Customization available upon request
Application examples
Spatial light modulators
Optical switches
Holographic recording
Optical waveguides
Main properties
Chemical formula: Fe:LiNbO3
Crystal structure: Trigonal, 3m
Density: 4,64 g/cm3
