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.
Abstract translation: 一个可控的Pockels电池系统有一个可以向Pockels电池施加电压的开关单元。 Pockels电池系统还具有一个延迟单元，可以在从Pockels电池施加电压或从电压中去除电压时设置精确的时间。 这允许在时间上移动施加到Pockels单元的电压脉冲，以这种方式也可以利用位于Pockels单元后面的分析器在时间上移位Pockels单元的传输脉冲。 因此，可以单独地控制所选择的激光脉冲的幅度。 开关单元可以是简单的推挽电路或由两个推挽电路制成的桥接电路。
