EO Device Crystal Lithium Niobate LINBO3 Crystals
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.
