Optical Grade LiNbO3 Crystal is widely used as frequency doublers for wavelength > 1μm 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...
