Potassium Dihydrogen Phosphate (KDP) and Potassium Deuterium 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.

ADVANTAGES

-   Good UV transmission

-   High optical damage threshold

-   High birefringence

-   High nonlinear coefficients

APPLICATIONS

-   Laser frequency conversion — harmonic generation for high pulse energy,

-   Electro-optical modulation

-   Q-switching crystal for Pockels cells
