Product description

Offering a voltage contrast ratio that is greater than 1000:1 at 1064 nm. Utilizing a dual crystal geometry, Chiron Pockels Cells have a low driving voltage (~2.3 kV quarter-wave voltage at 1064 nm for the Chiron 3).

The Chiron series is ideal for high average power systems due to low absorption that results in reduced thermal lensing and reduced depolarization. Low absorption is achieved with superior crystal quality and we accomplish this by utilizing proprietary techniques for crystal growing, fabrication, and polishing techniques to provide reliable, high-performing Pockels cells.

Chiron Pockels cells work in regenerative amplifiers, high pulse repetition rate micro-machining lasers, and high-average power lasers for material processing and metal annealing, as well as any other high power laser application.
