DKDP & KDP Crystal Description

Potassium Dideuterium Phosphate (DKDP) and Potassium Dihydrogen Phosphate (KDP) are nonlinear optical materials (NLO) know for their large NLO coefficients, wide transparency range, and high optical damage threshold.

These materials are widely used as frequency multipliers for the generation of the second, third, and fuorth harmonics for Nd: YAG, Nd: YLF lasers. Both crystals are also applied in electro-optics: as Q-switches for Nd: YAG, Nd: YLF, Ti: sapphire and Alexandrite lasers, and Pockels cells.
