Description
The QBD-BT series Pockels cell driver is a laboratory encased solution for generating high voltage pulses with precision and reliability. Designed for both pull-down (QBD-BT-…-DN) and push-up (QBD-BT-…-UP) schemes, these drivers are engineered to deliver fast risetimes and falltimes (leading edge) of less than 20 nanoseconds. With adjustable voltage amplitudes, these drivers provide flexibility and control, ensuring optimal performance for various applications.
One of the standout features of the QBD-BT series is its ability to operate at high repetition rates, ranging from single shots to over 100 kHz. This capability makes it suitable for demanding environments where rapid pulse generation is critical. The high voltage pulse amplitude is adjustable within a specified range, allowing users to tailor the output to their specific needs. Furthermore, the recovery time is efficiently managed between 5 to 10 microseconds, depending on the HV pulse amplitude and load capacitance.
The front panel of the QBD-BT series is designed for user-friendly operation, featuring a POWER switch, VOLTAGE and REP. RATE indicators, and buttons for adjusting these parameters. The module can operate in either internal or external synchronization modes, providing versatility in pulse initiation. Internal mode utilizes an internal clock, while external mode relies on TTL synchronization pulses. The back panel includes a MAINS connector for power, an HV OUTPUT connector for load connection, and an RS-232 connector for computer interfacing, ensuring comprehensive connectivity options.
Technical performance is highly dependent on load capacitance, with optimal results achieved at 23pF or lower. The module's output is bipolar, meaning a 4kV pulse is formed by applying +2kV to the positive output wire and -2kV to the negative. This bipolar configuration is crucial for understanding the voltage differences described in the module's specifications.

Frequently Asked Questions
The QBD-BT series Pockels cell driver is a device that produces high voltage pulses with high repetition rates, fast risetimes or falltimes, and adjustable voltage amplitude. It is available in two modifications: QBD-BT-…-DN for pull-down scheme and QBD-BT-…-UP for push-up scheme.
The typical risetime and falltime for the QBD-BT series are less than 20 nanoseconds, measured at the 10-90% level.
The recovery time for the QBD-BT series Pockels cell driver is between 5 to 10 microseconds, depending on the HV pulse amplitude and load capacitance.
The QBD-BT series driver can be synchronized in two modes: internal synchronization mode, where output pulses are initiated by an internal clock, and external synchronization mode, where output pulses are initiated by TTL synchronization pulses applied to the SYNCHRO connector.
The repetition rates for the QBD-BT series range from single shot to 100 kHz and higher, depending on the HV pulse amplitude and load capacitance.
The QBD-BT series driver requires a mains connection of 100-240 VAC, 50/60 Hz, and it includes a 5A fuse.
The performance of the QBD-BT series driver greatly depends on load capacitance. Full performance is achievable with a load capacitance of 23pF or below. Higher load capacitance decreases the maximal allowed repetition rate.
