Abstract
A controllable Pockels cell system has a switching unit that can apply voltage to the Pockels cell. The Pockels cell system also features a delay unit that enables setting of a precise time when voltage is applied or removed from the Pockels cell. This allows displacing in time the voltage pulse applied to the Pockels cell, in this manner also displacing in time the transmission pulse of the Pockels cell with an analyzer located behind the Pockels cell. Thus it is possible to individually control the amplitude of selected laser pulses. The switching unit can either be a simple push-pull circuit or a bridge circuit made from two push-pull circuits.
