Historically the Impact series was the first affordable high-end Pockels Cell for flashlamp-pumped lasers, and today it offers market-leading Q-switching and pulse-picking properties with its combination of an intrinsic contrast ratio of >4000:1 at 1064 nm and a voltage contrast ratio of greater than 3500:1 at 1064 nm.
The Impact 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 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.
