BBO CrystalPosted by Ningliu on May 13th, 2017 The BBO Crystal is an efficient NLO crystal for the second, third and fourth harmonic generation of Nd:YAG lasers, and the best NLO crystal for the fifth harmonic generation at 213 nm. Conversion efficiencies of more than 70% for SHG, 60% for THG and 50% for 4HG, and 200 mW output at 213 nm (5HG) have been obtained, respectively. BBO Crystal has the following. Advantages of BBO Crystal
Specifications Aperture: 2x2 ~ 25x25mm Lenght: 0.01 - 25mm Cutting Angle of BBO Crystal 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 BBO 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 S/D Parallelism: < 20 arc seconds Perpendicularity: < 5 arc minutes Wavefront Distortion: <λ/8 at 632.8nm Clear Aperture: Central 95% Chamfer: 0.15x45° Coating: * Protective coating is required to prevent polished surfaces from fogging. * Anti-reflective coating should be considered if low reflectivity is required.
