Download manual (1 MB)The Pockels cell driver HVSW-03 is a dedicated high voltage high repetition rate driver for pico- and femtosecond lasers. It represents a combination of two fast drivers (based on MOSFET technology) in a full-bridge schema. The primary use is for extracting single pulses from a pulse train.
Using the driver one chooses between two operation modes:
- fixed width short pulses (about 10-15 ns), triggered by a leading edge of an external TTL.
- variable width long pulses (adjusted in range of 100-2200 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.
The maximum output voltage is 2 kV bipolar, the maximum repetition rate is up to 1-2 MHz (in dependence on output voltage, cooling conditions and device modification). Driver’s bottom surface is a heat dissipating area for cooling the device, so we recommend using either a massive chassis, a heat sink or a cold plate to attach the driver.
The Pockels cell driver HVSW-03 requires +24 V DC power supply and a pulse generator to set an operating frequency and pulse width (in variable pulse width mode). There is no need for a separate DC high voltage source. An output voltage level is set by user using an analogue interface or base interface RS-485 and provided PC software.
