Product overview
Lithium Niobate (LiNbO3) or LN Crystal is widely used as frequency doublers for wavelength over 1μm and optical parametric oscillators (OPOs) pumped at 1064 nm and quasi-phase-matched (QPM) devices. Additionally due to its large Electro-Optic (EO) and Acousto-Optic (AO) coefficients, LiNbO3 is the most commonly used material for Pockels Cell, Q-switches and phase nodulators, waveguide substrate, and surface acoustic wave (SAW) wafers, etc.Scitlion is able to offer
