  • Description
  • Properties

Lithium niobate (LiNbO3, LN) is a multi-purpose material in photonics and optoelectronics fields. It features a wide transparency range from 420 nm to 5,2 µm, excellent nonlinear, electro-optic, and piezoelectric properties. Most common applications include infrared range optical modulation and Q-switching, nonlinear frequency conversion of >1 µm wavelengths. Their electrical and optical properties can be adjusted using magnesium or zirconium dopants.
