Product description
The inspiration for the development of the QX 2035 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 2035 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.
The QX 2035 include an in-house grown KD*P crystal with transmission above 98% from long wave UV to near IR.
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
- Q-switching
