KTP CrystalPosted by Ningliu on May 13th, 2017 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 of KTP Crystal:
Specifications Capabilities of KTP Crystal: Aperture: 2x2 ~ 10x10mm Lenght: 0.1 - 20mm Cutting Angle q and f: Determined by different kinds of homonic generartion Phase matching type: Type I or Type II End Configuration: Plano/Plano or Brewst/Brewst or Specified Specifications of KTP Crystal: Angle tolerance: Δθ< ± 0.5°; Δφ< ±0.5° Dimensional Tolerance: (W ± 0.1mm) x (H ± 0.1mm) x (L + 0.2mm/-0.1mm) Flatness: <λ/8 at 633nm Surface Quality: 10/5 Scracth/Dig Parallelism: < 20 arc seconds Perpendicularity: < 5 arc minutes Wavefront Distortion: <λ/8 at 632.8nm Clear Aperture: Central 95% Chamfer: 0.15x45° Coating: a) * S1,S2: AR @ 1064 nm R<0.1% & 532nm R<0.25% b) * S1:HR @ 1064nm R>99.8% & HT@ 808nm T>95% S2:AR @ 1064 nm R<0.1% & 532nm R<0.25% Like it?
