WISOPTIC Release New Type BBO Pockels Cell with Double Crystals,
low half-wave voltage, short switching time,
BBO(Beta-Barium Borate, β-BaB2O4)based Pockels cells operate from approximately 0.2 – 1.65 µm and are not subject to tracking degradation. BBO exhibits low piezoelectric response, good thermal stability, and low absorption. Due to the low piezoelectric coupling coefficients of BBO, BBO Pockels cells function at repetition rates of hundreds of kilohertz. These Pockels cells work in regenerative amplifiers, high pulse repetition rate micro-machining lasers and high-average power lasers for material processing and metal annealing.

WISOPTIC has been granted of several patents for its technology of BBO Pockels cells. WISOPTIC’s mass products of BBO Pockels cell are gaining worldwide customers’ interest and trust for its high cost performance. Power supply and driver for BBO Pockels cell will be available soon.
