The QBU-BT series Pockels cell driver is a state-of-the-art device designed to deliver high voltage pulses with exceptional precision and flexibility. This advanced driver is ideal for applications requiring high repetition rates, fast rise and fall times, as well as adjustable voltage amplitude and pulse width. Its user-friendly interface allows for easy selection of voltage levels, operating frequency, and pulse width, either through RS-232 or directly from the front panel, offering seamless integration into various setups.

One of the standout features of the QBU-BT series is its versatile triggering options. Users can choose between an internal clock or an external device signal, providing flexibility in synchronization with other equipment. The driver’s performance is optimized for load capacitances typical to Pockels cells used in the laser industry, ensuring reliable and consistent operation.

It is important to note the bipolar nature of the module’s output, which means that a 4kV pulse is produced by generating +2kV on one output wire and -2kV on the other. This design consideration is crucial for understanding voltage differences as described in the product documentation. Additionally, the QBU-BT series includes a refresh mechanism to maintain optimal performance, which may introduce a slight delay in output switching if a command is received during the refresh period.

For accurate output voltage measurement, a symmetrical (differential) high voltage probe is recommended to prevent potential failures due to inappropriate equipment. The inclusion of differential probes in the measurement setup is essential, as they contribute to the overall load capacitance, which can impact the driver's performance.
