KDP/DKDP Crystal

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;
