Product description：
CASTECH provides drivers to complement our Pockels cell series. When receiving a certain frequency trigger signal, Pockels cell driver will generate a high voltage with same frequency. By working with a signal generator, the driver is suitable for industrial integration, and can also be controlled by computer (USB to RS-232), which is convenient for scientific research institutes and industrial users to operate intelligently. CASTECH's Pockels cells driver is compatible with the KD*P Pockels cells at low repetition frequency and the BBO Pockels cells at high repetition frequency(~1MHz),the minimum pulse width can reach ~20 ns (PCDH series). The waveform can be positive, negative, and square. CASTECH provides customized services.
Applications：
● BBO Pockels cells
● KD*P Pockels cells
● Pulse picker
