YCOB nonlinear crystals

Yttrium calcium oxy borate(YCa4O(BO3)3,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
