Potassium Dihydrogen Phosphate


Potassium Dihydrogen Phosphate (KDP, ger.: Kaliumdihydrogenphosphat or KH2PO4 is among the most widely-used commercial NLO material with wide transparency range, high birefringence and high optical damage threshold. KDP crystals 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.
