One of the challenges of manipulating laser pulses is handling the inherent high energies that can easily damage materials. Impurities in optical crystals are a severe limitation to the optical power that a Pockels cell can endure and that's why we grow the highest purity KD*P crystals (99%) for use in our Pockels cells.
The Centaur Series utilizes the finest strain-free, highly deuterated KD*P available on the market, grown in our facility in Cleveland, OH, USA. The low loss KD*P crystal, as well as high damage threshold solgel and dielectric AR coatings, results in high optical damage resistance Pockels cell, needed for reliable laser intracavity use.
The sealed, nitrogen-filled, compact design with ceramic apertures and premium UV-grade fused silica windows, wedged or plano parallel, ensures high transmission and contrast ratios over its long lifetime. The housing of the Pockels cell incorporates standard pin-type HV connectors that provide a quick connection for simplified system design and assembly.
The Centaur series is a dimensional drop-in replacement for the industry standard QX series Pockels cell.
