The devised driver electronics for the actual Pockels cell is specifically characterized such that two Pockels cells can be connected and simultaneously driven with a fast slope of 9.5 kV in less than 11 ns, even at high Laser repetition rates of up to 2 kHz. By using a push-pull switching arrangement, a variable and low-jitter impulse width from 80 ns to 2.3 μs is achieved. Due to the drive capability of the circuit, more than one Pockels cell can be cascaded whilst maintaining very fast switching performance.
