Product Description

KDP/DKDP(KD*P)
Potassium Dihydrogen Phosphate (KDP) and Deuterated Potassium Dihydrogen Phosphate (DKDP/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 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
