Detailed Description

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. KTP crystal also has high electro-optic(E-O) coefficient and low dielectric constant, and large figure of merit, these features make it also widely used in electro-optic application.________________________________________Advantages• Large Nonlinear Optical (NLO) Coefficients• Wide Angular Bandwidth and Small Walk-off Angle• Broad Temperature and Spectral Bandwidth• High Electro-Optic (E-O) Coefficient and Low Dielectric Constant• Large Figure of Merit for an Optical Waveguide Modulator• Nonhygroscopic, Good Chemical and Mechanical PropertiesCapabilities:Aperture: 2x2 ~ 10x10mmLenght: 0.1 - 20mmCutting Angle q and f: Determined by different kinds of homonic generartionPhase matching type: Type I or Type IIEnd Configuration: Plano/Plano or Brewst/Brewst or Specified
