Anti-Reflective Coated Quartz Window DKDP Pockel Cell Q Switch For
Low Repetition Rate DPSS Nd:YAG Lasers
Products Description:
Crystrong provides bulk supply of high quality KDP and DKDP
crystals in diverse sizes for the above applications, as well as
custom-made services of crystal select, design and processing.
Application of DKDP (KD*P) Electro-Optical Cell is as follows:
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.
Potassium Dihydrogen Phosphate (KDP) and Potassium Dideuterium
Phosphate (DKDP, KD*P) 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.
