Description

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.
Yttrium Calcium Oxyborate (YCa4O(BO3)3 or YCOB) is a good nonlinear crystal which is widely used in high power laser system. YCOB crystals have good nonlinear optical properties, such as larger effective NLO susceptibilities, larger Temperature Acceptance, relatively high damage threshold, less parametric luminescence, smaller thermal expansion coefficient, less anisotropy and high temperature piezoelectric properties. Besides, it is easy to grow large size crystal with high quality. YCOB crystal is suitable for applications in high energy and high power laser fields,including second-harmonic generation (SHG), third-harmonic generation (THG), optical parametric oscillator (OPO), optical parametric amplification (OPA),optical parametric chirped-pulse amplification (OPCPA). Another application is in the field of piezoelectric devices at high temperature. YCOB crystal has very high electric resistivity that can be fabricated as piezoelectric sensors working at the temperature as high as 1000ºC in aerospace engines.
