Description
HVSW-04 pulse picker is a dedicated high voltage high repetition rate Pockels cell driver for pico- and femtosecond lasers. It represents a combination of two fast drivers (based on MOSFET technology) in a full-bridge schema.
Using the pulse picker driver one chooses between two operation modes:
- fixed width short pulses (about 15-20 ns), triggered by a leading edge of an external TTL.
- variable width long pulses (adjusted in range of 100-2000 ns typically, other on request), when a leading edge of an external TTL signal cause rise of pulse, and a trailing edge cause pulse fall.
We offer also a Wide Range (WR) driver modification with a continuously adjustable in range of 15-2000 ns pulse width.
The driver requires +24 V DC power supply, a pulse generator to set an operating frequency and pulse width (in variable pulse width mode) and a HV DC bipolar power supply (e.g. HVPS-300 (+24V DC input) or HVPS-BT (100-240V AC input) from OEM Tech). User has a possibility to adjust an output voltage level by using an interface of the HV DC power supply.
The maximum output voltage is 4 kV (bipolar), maximum repetition rate is 0.5-4 MHz (depends on output voltage, actual load capacitance and cooling conditions).
The driver is water-cooled, but we have also an air-cooled HVSW-03, please, ask.
We offer the complete electrical modules kit for a pulse picker and ready to consult you about our products.

Frequently Asked Questions
The HVSW-04 is a high voltage high repetition rate Pockels cell driver.
This equipment may be dangerous, so it's important to read the entire user manual carefully before using the product.
The output should be measured with a symmetrical (differential) high voltage probe only. Using inappropriate equipment for measurement is a common cause of driver failure.
The HVSW-04 supports an analogue interface for operations and an RS-485 interface for communication.
The contents of delivery are detailed in the user manual, but specific items are not listed in the provided datasheet excerpt.
The technical specifications can be found on page 14 of the user manual.
Instructions on how to order the HVSW-04 are provided on page 16 of the user manual.
