KDP & DKDP Crystals

Potassium Dihydrogen Phosphate     (KDP)    and Potassium Dideuterium Phosphate (DKDP) are widely used for electro-optical modulation and frequency conversion.
INNOWIT’s KDP and DKDP have high nonlinear coefficient and high optical damage threshold, and can be used electro-optical modulator, Q switches and shutters for high speed photography.
Applications and Advantages:
  • Electro-optical modulator, Q-switches;
  • Second, third and fourth harmonic generation, frequency double for dye laser;
  • Shutter for high speed photography;
  • High power laser frequency conversion materials;
