Product Name: Optical Lithium Niobium Crystal (LN) Linbo3 Shipping: FedEx, DHL, UPS... Trademark: FineWin Transport Package: Single Piece or 25 PCS Specification: 2-6 inch Origin: China Product Description Description: Lithium niobate (LiNbO3) is a ferroelectric material suitable for a variety of applications. Its versatility is made possible by the excellent electro-optic, nonlinear, and piezoelectric properties of the intrinsic material. It is one of the most thoroughly characterized electro-optic materials, and crystal growing techniques consistently produce large crystals of high perfection.Applications:Frequency doubling for wavelengths >1μm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices;Pockel cells, Q-switches, and phase modulators;Waveguide substrates, surface acoustic wave (SAW) wafers.Physical and Optical Properties:Crystal StructureTrigonal, space group R3c Cell Parameters a=0.515,c=13.863,Z=6 Melting Point 1255 +/-5ºC Curie Point 1140 +/-5ºC Mohs Hardness 5 Density 4.64 g/cm3 Absorption Coefficient ~ 0.1%/cm @ 1064 nm Solubility insoluble in H2O Relative Dielectric Constant εT11/ε0: 85 εT33/ε0:29.5 Thermal Expansion ||a, 2.0 x 10-6/K @ 25ºC Coefficients at 25ºC ||c, 2.2 x 10-6/K @ 25ºC Thermal Conductivity 38 W /m /K @ 25ºC Transparency Range 420 - 5200 nm Refractive Indices ne= 2.146, no= 2.220 @ 1300 nm ne= 2.156, no= 2.322 @ 1064 nm ne= 2.203, no= 2.286 @ 633 m Optical Homogeneity~ 5 x 10-5/cm Sellmeier Equations( l in mm) no2(l) = 4.9048+0.11768/(l2- 0.04750) - 0.027169l2 ne2(l) = 4.5820+0.099169/(l2- 0.04443) - 0.021950l2 Specifications:Material Laser grade LiNbO3 Orientation ±0.5o Dimensional Tolerance±0.1mm Surface quality20/10 Scratch/Dig per MIL-O-13830BFlatnessλ/8 @ 633 nmPerpendicularity 5 arc min Parallelism better than 20 arc sec Clear Aperture > Central 90% AR Coating AR coating with R < 0.2% at center WavelengthProduct Pictures:
