KDP (Potassium Dihydrogen Phosphate ) and DKDP (Potassium Dideuterium Phosphate, KD*P) are among the most widely-used commercial NLO materials. With good UV transmission, high damage threshold, and high birefringence, these material are usually used for doubling, tripling and quadrupling of Nd:YAG laser. In addition, they are also widely used as E-O modulators such as Q-switch.
As an important KDP/DKDP supplier in the whole international market, Wisoptic confirms top quality, large quantity and fast delivery upon your request.
