switching appears on Pockels cell. This effect changes the polarization state of Pockels cell which blocks or deflects light from passing through the crystal. The speed of switching and voltage applied across the crystals will determine the pulse duration of the laser output (W. Koechner, 2006)
In this paper, a simple circuit of avalanche transistors was developed to switch in the kilovolt regime. A series avalanche transistor was designed to switch up to 4.5 kV within few nanoseconds.
