LiNbO3
LiNbO3Crystals is widely used as 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 Elector-Optic (E-O) and Acousto-Optic (A-O) coefficients, LiNbO3crystal is the most commonly used material for Pockel Cells, Q-switches and phase modulators, waveguide substrate, and surface acoustic wave (SAW) wafers, etc.
Applications :
Integrated Waveguide Photonics
Wave Guide Lasers
Polarizer for Optic Isolator
EO Waveguide Phase Modulators
EO Waveguide Amplitude Modulators
Quasi-phase Matching for SHG and OPO
