20 year experience servicing the most demanding laser applications with KD*P and KDP including large aperture Pockels cell (dia>20 mm) for high power laser system (e.g. ICF)
KDP, KD*P, KTP, RTP, BBO, and LN are grown by WISOPTIC in-house
Being purchased and trusted by dozens of laser companies worldwide
Potassium Dihydrogen Phosphate (KDP) and Potassium Dideuterium Phosphate (DKDP) are among the most widely-used commercial NLO materials, characterized by good UV transmission, high damage threshold, and high birefringence, though their NLO coefficients are relatively low. They are usually used for doubling, tripling or quadrupling of a Nd:YAG laser (at constant temperature). With excellent optical homogeneity and high E-O coefficients, KDP and DKDP crystals are also widely used in E-O modulators, Q-switches, etc.
Application of DKDP Series Pockels Cell ：
With excellent physical and optical property, DKDP series Pockels cells are widely used in laser systems with large caliber, high power and narrow pulse width. They are among the optimal E-O Q-switches used in pulse laser systems, including: OEM laser systems; Medical/cosmetic lasers; Versatile R&D laser platforms; Military & aerospace laser systems.
WISOPTIC has been granted of dozens of patents for its technology of DKDP Pockels cells such as the integrated Pockels cell (with polarizer and λ/4 wave plate inside) which can be easily assembled into Nd:YAG laser system and helps to make laser head more compacted and cheaper.
Applications:
● Q-switching ● Regenerative amplifier ● Pulse picker ● Cavity dumping
● Beam chopper ● High speed optical switch ● Optical power stabilizer
