Z-Cut Optical Ln Linbo3 & Lt Litao3 Crystal Ingot Lithium Tantalate Lithium Niobium Crystal Boule

>> Product Description
Optical Lithium Niobate(LiNbO3) Crystal lens is widely used as frequency doublers for wavelength > 1 mm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices. Due to its large Electro-Optic (E-O) and Acousto-Optic (A-O) coefficients.

We manufacture LiNbO3 crystal professionally.

Mohs Hardness: 55

Dielectric Constant: E11/e0 = 85; E33/e0 = 29.5
Thermal Conductivity: 38 W/m/° C at 25° C
Thermal Expansion Coefficient: A1=a2 =2X10-6/° C, a3=2.2X10-6/ ° C at 25° C
Piezoelectric Strain Constant: D22 = 2.04 X 10-11 C/N, d33 = 19.22 X 10-11 C/N
Elastic Stiffness Constant: CE11 = 2.04 X 1011 N/m2, CE33 = 2.46 X 1011 N/m2<o: P>
