MgO LiNbO3 Nonliear Crystals
DescriptionSome applications of pure MgO:LiNbO3 crystal are limited by its relative low optical damage threshold. While when doped with 5mol% magnesium oxide,Website:, MgO:LiNbO3 crystal shows 1-2 orders of magnitude increase in optical damage threshold, coercive field for domain reversal also decreases from 21KV/mm to 6KV/mm below, UV-absorption edge position shifts to 310nm and OH-infrared absorption peak to 3535cm-1,which greatly develops the application of MgO:LiNbO3 crystal. We can provide MgO:LiNbO3 crystal wafers, crystal blocks and bars with various specifications. Crystal defects and distributions of refractive index are strictly examined.SpecificationPolishing Specification for Laser GradeⅠOrientation Tolerence< 0.5°Thickness/Diameter Tolerance±0.1 mmSurface Flatness<λ/8@632nmWavefront Distortion<λ/4@632nmSurface Quality20/10Parallel30〞Perpendicular15ˊClear Aperture>90%Chammfer<0.2×45°Polishing Specification for Laser Grade ⅡOrientation Tolerence< 0.2°Thickness/Diameter Tolerance±0.02 mmSurface Flatnessλ/10@632nmWavefront Distortion<λ/8@632nmsurface Quality10/5Parallel10〞Perpendicular5ˊClear Aperture>90%Chammfer<0.2×45°
