DKDP Pockels Cells

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.
