A gas discharge device includes a block having one or more gas filled cavities or passageways along which the laser beams may propagate. Coupled to one of these passageways is an exit port which is coupled to a cathode mounted on an outer surface of the block. The exit port is formed so that the cross-section of the exit port decreases with distance from the outer surface of the block.

A gas discharge device comprising: a block having interconnected cavities forming at least a first passageway and an exit port for containing a gas and through which a gas discharge is to take place, said exit port having first and second end portions where said first end portion is in communication

A gas discharge device comprising: a block having interconnected cavities forming at least a first passageway and an exit port for containing a gas and through which a gas discharge is to take place, said exit port having first and second end portions where said first end portion is in communication with said first passageway to permit the flow of gas therebetween, and said second end portion has a common interface with a first outer surface of said block, said second end portion having a cross-sectional area greater than said first end portion an anode in communication with said gas; and a cathode including a housing having a mounting surface and a cavity extending inwardly from said mounting surface, said cathode cavity having an inner surface composed of a low sputtering electron emitting material, and said mounting surface secured to said block outer surface to form a gas tight seal and positioned such that said cathode cavity is in communication with said second end portion of said exit port to permit gas flow therebetween.
