Description Features

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.
Altechna offers crystals with different Fe doping concentration, dimensions and optical processing requirements. Other dopants are available upon request.
