Product Details

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:

l   Good UV transmission

l   High optical damage threshold

l   High birefringence

l   High nonlinear coefficients

APPLICATIONS:

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

l   Electro-optical modulation

l   Q-switching crystal for Pockels cells
