Description
HVSW-03 Pockels Cell Driver with Embedded Power Supply
The HVSW-03 is an advanced Pockels cell driver meticulously designed for optimal performance with pico- and femtosecond lasers. This device is used for pulse picking and controlling regenerative amplifiers, ensuring precision and reliability in demanding laser applications.
With a maximum output voltage of 2kV, the HVSW-03 can achieve repetition rates of up to 2MHz at reduced output voltages around 1kV. Its rapid transition times, ranging from 6 to 8 nanoseconds, depend on the load capacitance and the driver's configuration, making it a versatile choice for various laser setups. The HVSW-03 features a compact design, which facilitates easy integration into existing systems.
It employs conductive cooling through its bottom surface, enhancing its thermal management capabilities. The embedded high voltage power supply, requiring a simple +24V DC input, adds to its convenience and efficiency. The driver is equipped with both analogue and RS-485 interfaces, and configuration software compatible with Windows OS is available to streamline setup and operation. This Pockels cell driver is engineered to deliver exceptional performance, particularly with load capacitance typical to Pockels cells used in the laser industry, ranging from 5 to 7pF.
The module's bipolar output, formed by applying +1kV to one output wire and -1kV to another, ensures precise control over voltage differences. Sequential output pulses alternate polarity by default, thanks to the full bridge schema, providing flexibility for various operational requirements. For users needing fixed polarity, a modified version is available. Additionally, the driver offers adjustable pulse widths from 15ns to 2200ns, with options for extended range modifications to suit specific needs.
