Fe:LiNbO3
is common photorefractive materials.
It has large electro-optic (E-O)
coefficients, high photorefractive
sensitivity and high diffraction efficiency.
Because of its easy operation, storage, low
cost and large available size, Fe:LiNbO3
is suitable for volume fabrication and
practical devices.
We supplies high quality Fe:LiNbO3
crystals, which are all poled and strain and
scatter free. The iron level we can provide
is from 0.005 to 0.20mol% with size
40x40x40mm or 3" in diameter
