System for attenuating the electromagnetic pulse generated in a high power laser setup

Abstract

A device attenuates an electromagnetic pulse generated in an installation in which a high-power laser beam is sent to a target mounted on a target support. The device includes an electrically conductive plate, electrically connected to an electric earth of the installation and to which the target support is fixed, a plate of material which absorbs electromagnetic waves fixed to one face of the electrically conductive plate located on the target support side and a device for passing a discharge current, which is the result of an interaction of the laser beam with the target, between the target and the electrically conductive plate, where the device for passing the discharge current is equipped with a device for attenuating the current.
