Potassium Dihydrogen Phosphate (KDP) and Potassium Dideuterium Phosphate (KD*P ) are among the most widely-used commercial NLO materials. They 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.
- Good UV transmission
- High optical damage threshold
- High birefringence High nonlinear coefficients

Note:
1. KDP, KD*P&LiIO3 is highly hygroscopic and the coating can not be available. Please keep it in a dry environment, and sealed housing is recommended.
2.KD*P & KDP are among the most widely-used commercial NLO materials, characterized by good UV transmission, high damage threshold, and high birefringence, though their NLO coefficients are relatively low.Because their polished surfaces are easy subject to moisten, the user recommends a dry condition (<50%) and the sealed housing for preservation.
Note: The LiIO3 crystals is available too.
