Product description

These Pockels cells offer a voltage contrast ratio that is greater than 2000:1 at 1064 nm. Impact Pockels cells have a compact design with robust ceramic apertures and premium UV-grade fused silica windows for high transmission and contrast ratio in demanding applications.

The Impact series utilizes the finest strain-free, highly deuterated KD*P available, grown in our own crystal growth facility, as well as high damage threshold solgel and dielectric AR coatings for high optical damage resistance. connectors for high-voltage applications The housing of the Pockels cell incorporates standard pin-type HV connectors that provide a quick connection for simplified system design and assembly. Conventional threaded connectors are available as an option.
