            福州高特光電科技有限公司

            LiNbO 3; Crystal is widely used as frequency doublers for wavelength > 1 mm 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。
            FOCtek provides high quality and large size LiNbO3 crystals for laser frequency doublers, OPOs and quasi-phase-matched doublers, as well as waveguide substrate and SAW wafers. High quality LiNbO 3; finished components with aperture of (2 - 15) x (2 - 15) mm2 and length up to 50 mm for frequency doublers and optical parametric oscillators (OPOs), 50x50x1 mm3 or Dia. 3" x 1 mm LiNbO3 substrate for waveguide optics, and Dia. 3" SAW wafers are available with high volume and at low price.
