  • Description
  • Properties

Lithium niobate (LiNbO3, LN) is a multi-purpose material in photonics and optoelectronics fields. It features wide transparency transparency range from 420 nm to 5,2 μm, excellent nonlinear optics, electrooptics 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 by magnesium or zirconium dopants.
