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.
