LiNbO3 crystals are widely used as frequency doublers for wavelengths > 1mm and optical parametric oscillators (OPOs) pumped at 1064nm as well as quasi-phase-matched (QPM) devices. Due to their large Electro-Optic (E-O) and Acousto-Optic (A-O) coefficients, LiNbO3 crystals are the most commonly used material for Pocket Cells, Q-switches and phase modulators, waveguide substrates, surface acoustic wave (SAW) wafers, etc.
PHOSCTECH provides high quality, large LiNbo3 crystals for laser frequency doublers, OPOs and quasi-phase-matched doublers, waveguide substrates and SAW wafers. High quality LiNbo3 components with apertures of (2-15) x (2-15) mm2 and lengths up to 50mm for frequency doublers, OPOs 50x50x1mm3 or diameters of 3″x 1mm3 LiNbo3 substrate for waveguide optics, and 3″ diameter SAW wafers are available in high volumes at low prices.
PHOSCTECH provides high quality MgO:LiNbo3 crystals for various nonlinear optics (NLO) and E-O applications. The typical size of MgO: LiNbo3 crystals is (3-10) x (3-10) x (10-30) mm3 for OPOs and OPAs and frequency doubling and mixing, and 20x20x1mm3 for waveguide substrates. Other specifications and AR coatings for MgO: LiNbo3 are available upon request.
