Low absorption: ＜1000ppm/cm electrical conductivity: about 10-10Ω High damage threshold: ≥2 conversion efficiency: up to 80% depending upon cube length and laser system Gray-tracking at high power limited its application to moderate power densityĪdditional applications for large size GTR-KTP nonlinear crystal include mixed frequency, electro-optical modulation, optical parametric generation, and the optical waveguide. Low cost compare with BBO and LBO Disadvantage: High thermal conductivity (2 times that of BNN crystal ) Wide angular bandwidth and small walk-off angle Large nonlinear optical coefficients(15 times that of KDP) Honour Optics is the professional high quality Chinese KTP nonlinear crystal manufacturer, purchasing large size KTP nonlinear crystal at factory price.Įfficient frequency conversion(1064nm SHG conversion efficiency is about 80%) GTR-KTP crystal has wide angular bandwidth and small walk-off angle and broad temperature and spectral bandwidth.
When working under the laser of 532nm, GTR-KTP would not form a gray tracking over the light path, then it can keep the SHG laser energy the same as the beginning. Honour Optics also offer GTR-KTP crystal, GTR-KTP crystal is GRAY TRACKING RESISTED KTP crystal, which has similar nonlinear, physical and chemical properties with normal KTP crystal, but has better gray tracking resisting property. KTP crystal also has high electro-optic(E-O) coefficient and low dielectric constant, and a large figure of merit, these features make it also widely used in the electro-optic application. Potassium Titanium Oxide Phosphate (KTiOPO4 ), or KTP crystal is mostly used as nonlinear crystals for frequency doubling of solid-state Nd: YAG crystal or Nd: YVO4 crystal laser, as it has large nonlinear optical coefficients, wide angular bandwidth, and small walk-off angle, broad temperature and spectral bandwidth.
