Lithium niobate (LiNbO3) crystals exhibit excellent electro-optic and nonlinear optical properties. Their electro-optic coefficient (for example, r₃₃ = 30.90 pm/V) and nonlinear optical coefficient (d₃₁ = 33 pm/V) make them outstanding for high-speed optical modulation and laser frequency conversion. Additionally, the wide optical transparency range (400 to 5000 nm) and stable thermal characteristics of lithium niobate enable its extensive applications in optical communication, optical storage, and laser technology.
