YCOB nonlinear crystalsYttrium calcium oxy borate(YCa4O(BO3)3,Website:http://www.meta-laser.com,YCOB)crystal was good materials for nonlinear optical and high temperature piezoelectric applications. Features: • No deliquescence; • Larger effective NLO susceptibilities; • Larger Temperature Acceptance; • High laser induce damage threshold; • Less parametric luminescence (three orders less); • Smaller thermal expansion coefficient and less anisotropy; • Very high electric resistivity Applications • Second-harmonic generation (SHG); • Third-harmonic generation (THG); • Optical parametric oscillator (OPO) • Optical parametric amplification(OPA) • Optical parametric chirped-pulse amplification (OPCPA). • Piezoelectric devices Meta-Photonics YCOB Crystals • Grown by CZ method; • Maximal Size: dia100mm • Custom design prouction is availableSpecificationPolishing Specification for Laser GradeOrientation Tolerence< 0.5°Thickness/Diameter Tolerance±0.01 mmSurface Flatness<λ/8@632nmWavefront Distortion<λ/4@632nmSurface Quality10/5Parallel30〞Perpendicular15ˊClear Aperture>90%Chammfer<0.2×45°Standard products
