Photorefractive Crystal

Iron doped Lithium Niobate (Fe:LiNbO3)

Lithium Niobate crystals doped with iron Fe:LiNbO3 are an excellent photorefractive material with high electro-optical coefficients and high photorefractive sensitivity and diffraction efficiency without an applied electric field. The crystals have wide applications in phase conjugation and holographic recording.

Crystals with different Fe doping concentration, dimensions and optical processing requirements can be supplied.
