Lithium Niobate - LiNbO3 Crystals With CR-AU Coating


LiNbO3 (Lithium niobate, LN) crystal is a negative uniaxial crystal and one of the most thoroughly characterized optical materials. With its wide transparency range in the visible and mid-infradred and the excellent chemical and mechanical stability, LN crystal can be used as a bifrengent material for applications in infrared.


With its large electro-optic coefficients, wide optical transparency window, and availability of high optical quality crystals, LN (lithium niobate) crystal is often the material of choice for optical modulation and Q-switch at near-infrared and infrared wavelengths. For electro-optic modulators (EOM) the crystal can be z-cut with zero residual birefringence along the direction of light propagation or x-cut with non-zero residual birefringence and the maximized effective electro-optic coefficient. For Q-switch the crystal is typically z-cut with zero residual birefringence and an electric field is applied transverse to the direction of light propagation. The piezoelectric ringing in LN is a disadvantage at high repetition frequency, but can be overcome to some extent with proper piezoelectrically damped designs.


Crystro's LN crystal boule is grown by Czochralski method.Max diameter reach 4inch,we can custom size and specs accordding to custmer's requstsm,also can do AR coating and CR-AU electrodes.

Crystro provides:

  • LiNbO Wd3 wedges used for fiber optical isolators and circulators.
  • Reliable delivery
  • Strict quality control
  • Technical support
  • Very competitive prices
