KDP-DKDP Crystal Feature Potassium Dihydrogen Phosphate (KDP) and Potassium Dideuterium Phosphate (KD*P ) are among the most widely-used commercial NLO materials. They are commonly used for doubling, tripling and quadrupling of Nd:YAG laser at the room temperature. In addition, they are also excellent electro-optic crystals with high electro-optic coefficients, widely used as electro-optical modulators, Q-switches, and Pockels Cells, etc. 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:20/10 Scracth/Dig Parallelism:< 20 arc seconds Perpendicularity:< 5 arc minutes Wavefront Distortion:<λ/8 at 633nm 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.
