Abstract
A high voltage switch for discharging a storage capacitor to increase the voltage across a pockels cell includes a plurality of semi-conductor devices conducted in series with the pockels cell and the capacitor, each of the semiconductor devices having a control input; a plurality of fast, light responsive devices connected to the control input of each semiconductor device of the plurality of semiconductive devices respectively for switching the respective device from a non-conducting state to a conducting state; and a controlled, fast rise time light source optically coupled to all of the fast light responsive devices for simultaneously triggering all of the semi-conductor devices.
