QX Pockels Cells
Clamped rugged housing that minimizes piezo-optical ringing is the star feature of the QX Pockels Cell series. This Pockels Cell series is designed to operate at repetition rate up to 3 kHz, higher than that of the Impact Pockels Cell line. The QX series include an in-house grown KD*P crystal with transmission above 98% from long wave UV to near IR.

Product description
The inspiration for the development of the QX Pockels cells is the customer’s need to operate at higher repetition rates compared to the Impact Pockels cell line. With repetition rates up to 3 kHz, the QX series of Pockels cells offer a voltage contrast ratio greater than 2000:1 at 1064 nm. In addition, the QX Pockels cells are equipped with ceramic apertures for robustness 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 functionality and are supplied with a QA inspection report and suggested alignment procedures.
Options
- Attenuated version to allow for 10 kHz modulation frequency
- Window and sol gel coatings with choice of operational wavelengths
- KD*P crystals other than 99% deuteration available at a reduced price
Applications
