KDP Pockels cell

Economically priced Compact size Low absorption Transmission from 400 nm to 1100 nm Applications: Q-switching of the laser cavity Cavity Dumping Pockels cells are used to change the polarization state of light passing through it when a voltage is applied to the electrodes of electro-optic crystals such as KD*P. When used in conjunction with polarizer, Pockels cells can be used as fast optical switches. Typical applications include Q-switching of the laser cavity, laser cavity dumping and coupling light into and from regenerative amplifiers. KD*P based Pockels cells are routinely 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 KD*P based Pockels cell for laser cavity Q-switching. Electro-optical KD*P crystals have high laser power resistant dielectric AR coatings. Additionally PC12SR and D-compact series Pockels cells have AR coated windows for improved lifetime and protection in less user friendly environment.
