ABSTRACT:
An improved electrical gap switch for use with pulsed gas discharge lasers. The closure of a spark gap, railgap, or other multichannel switch is triggered by the application of a second voltage in combination with the primary voltage that is closed by the switch. The second voltage is of opposite polarity and applied to an electrode opposite from that to which the primary voltage is applied. The second voltage has a more rapid rise time than that of the first, and its application to the switch is momentarily isolated from the load by a saturable inductor. Following triggering of the switch by the combination of voltages, the inductor saturates and provides a low impedance path for the voltage and charge from the primary source to the load.
