KDP&K*DP
KDP&K*DP
KDP and KD*P are among the most widely-used commercial NLO materials, characterized by good UV transmission, high damage threshold, and high birefringence.
They are usually used for doubling, tripling and quadrupling of a 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, such as Q- switches, Pockels Cells, etc.
