HGTR-KTP (Highly Gray Trace Resistant KTP) – Nonlinear Crystal – Customized Products
HGTR-KTP (Highly Gray Trace Resistant KTP) nonlinear crystal, the direct manifestation of gray trace is the appearance of black or gray damage traces inside the crystal, while HGTR-KTP nonlinear crystal greatly reduces the Ti+3 ion center defect inside the crystal during laser frequency doubling, its nonlinear optical coefficient, high thermal conductivity, small mismatch and small walking away angle, no deliquescence, stable chemical and mechanical properties, is now widely used in Nd:YAG and Nd:YVO4 lasers with 1064-532 nm wavelengths are widely used as frequency doubling crystal materials. In addition, it can also be used to make components for frequency doubling, frequency mixing, electro-optical modulation, optical parametric oscillation and optical waveguide.
