KDP and DKDP Nonlinear Crystals
KDP and DKDP Nonlinear Crystals
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.
Key Features and Applications
- Good UV transmission
- High optical damage threshold
- High birefringence
- High nonlinear coefficients
- Laser frequency conversion — harmonic generation for high pulse energy,
- Electro-optical modulation
- Q-switching crystal for Pockels cells
