HVR-Drive™ Rack-Mounted Pockels Cell Driver
A turnkey integrated driver and control system to switch Pockels cells used for pulse management in high repetition rate ultrafast laser regenerative amplifiers.
Full Product Description- Input voltage:
- Min: 88 VAC, Max: 264 VAC
- Input frequency:
- Min: 50 Hz, Max: 60 Hz
Product description
This driver has a repetition rate from 0–200 kHz, an output voltage of 0–7.5 kV, rise and fall times of 10–15 ns with pulse widths of 100 ns–5 μs. The driver produces a top-hat waveform with fast-rising and falling edges.
A built-in digital voltmeter allows you to set the output voltage before applying it to the driver and separate high voltage enable/disable buttons are standard for added safety. A separate trigger on/off switch provides easy pulse control which also disables the high voltage at the rear panel output connectors.
The HVR-System comes in a standard 483 mm (19”) rack-mount enclosure which can also be used as a benchtop unit. It comes with forced air cooling for operation up to 50 kHz or water-cooled for higher repetition rates.
