pk10开奖记录 BBO Pockels Cells

Pockels Cells are used to change the polarization state of light passing through it when a voltage is applied to the electrodes of electro-optic crystals. BBO Pockels Cells operate from approximately 0.2 to 1.65 µm and aren't subject to tracking degradation. Due to the low piezoelectric coupling coefficients of BBO, our cells function at repetition rates of hundreds of  kilohertz.
The product series BBO Pockels Cells employs single crystal , dual crystal and low-voltage geometry. Moreover, we also provide different types of products and customized services to meet customer needs.

    Pockels Cells are used to change the polarization state of light passing  through it when a voltage is applied to the electrodes of electro-optic crystals. Castech BBO Pockels Cells are the better alternative to KD*P Pockels Cells for high average power and high repetition rate applications. BBO Pockels Cells operate from approximately 0.2 to 1.65 µm and aren't subject to tracking degradation. Due to the low piezoelectric coupling coefficients of BBO, our cells function at repetition rates of hundreds of  kilohertz. The product series BBO Pockels Cells employs single crystal , dual crystal and low-voltage geometry. Moreover, we also provide different types of products and customized services to meet customer needs.
