DKDP POCKELS CELLS
DKDP (KD*P) Pockels cells are used in most of the commercially available flashlamp pumped Nd:YAG and Ruby lasers, low repetition rate DPSS lasers.
Pockels cells are used to change the polarization state of light with a voltage applied to the electrodes of electro-optic crystal such as DKDP (KD*P).
DKDP (KD*P) based Pockels cells are used for Q-switching applications from the 400 nm to about 1.1 μm. Most of commercial flashlamp pumped Nd:YAG lasers and low repetition rate DPSS Nd:YAG lasers are equipped with DKDP (KD*P) based Pockels cells for laser cavity Q-switching.
Features of DKDP (KD*P) Pockels cells:
Low absorption and high deuteration material
High damage threshold dielectric AR coatings for requested wavelengths
Operating voltage does not depend on crystal aperture, so large apertures are available
Suitable for fs applications due to low GVD
Single-crystal based three terminal design available upon request
Applications:
Q-switching of flashlamp pumped high energy and low repetition rate diode pumped lasers
Pulse picking
Laser cavity dumping
Electro-optical DKDP (KD*P) crystals used in DKDP (KD*P) Pockels cells have high laser power resistant dielectric AR coatings. Additionally, PC12SR, D-compact and D-mini series Pockels cells have AR coated windows for improved lifetime and protection in less user friendly environment.
