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 ?
