Description
The QBU-10kV Pockels Cell Driver series, including models QBU-9036, QBU-8032, and QBU-7028, is engineered to deliver high-voltage pulses with exceptional repetition rates, fast rise and fall times, and customizable voltage amplitude and pulse width. These drivers are capable of generating output voltages up to 10 kV, making them suitable for applications that require half-wave voltage schemes or involve larger crystals.
Designed for efficiency and versatility, these modules operate with a +24 V DC power supply and require a pulse generator to define the operating frequency and pulse width. The QBU series offers flexibility with two control types: manual and automatic. Users can manually adjust the output voltage using an onboard configuration trimpot or opt for remote control by applying a DC voltage to the designated pin, allowing for seamless integration into various operational setups.
The QBU-10kV series stands out for its adaptability to different load capacitances, particularly those typical in the laser industry, such as 5-7pF. This adaptability ensures optimal performance, although it should be noted that higher load capacitance may reduce the maximum permissible repetition rate. The bipolar nature of the module's output is another noteworthy feature, as it generates pulses by producing equal but opposite voltages on two output wires. This design consideration is crucial for users to understand the voltage difference descriptions provided.
The output is triggered by an arbitrary external TTL signal, i.e. it is possible to set a pulse width for every pulse
