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:
- Compact size
- Low absorption
- Transmission from 400 nm to 1100 nm
Applications:
- Q-switching of the laser cavity
- Cavity dumping
- Coupling light into and from regenerative amplifiers
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.
