Product description

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

The QX series employs broadband, high damage threshold solgel AR coating for improved durability and performance. All units are tested for optic and electric function and are supplied with a QA inspection report and suggested alignment procedures.
