LiNbO3 crystal has very good mechanical and physical properties as well as high optical homogeneity. It has been extensively used in fiber optics with stable quality. LiNbO3 Crystal is also high quality frequency doublers for wavelength > 1um 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, LiNbO3 crystal is the most commonly used material for Pockel Cells, Q-switches and phase modulators, waveguide substrate, and surface acoustic wave (SAW) wafers, etc.Jinsheng optoelectronics is able to offer you high quality optical grade LiNbO3 crystals up to 4?in diameter and related products with competitive prices.
