ABSTRACT:
A gas discharge laser includes a laser chamber containing a halogen laser gas, two electrode elements defining a cathode and an anode, each having a discharge receiving region defining two longitudinal edges and having a region width defining a width of an electric discharge between the electrode elements in the laser gas. The anode comprising a first anode portion comprising a first anode material defining a first anode material erosion rate, located entirely within the discharge receiving region, a pair of second anode portions comprising a second anode material defining a second anode material erosion rate, respectively located on each side of the first anode portion and at least partially within the discharge receiving region; an electrode center base portion integral with the first anode portion; and wherein each of the respective pair of second anode portions is mechanically bonded to the center base portion.
