ELECTRODES FOR FLUORINE GAS DISCHARGE LASERS

摘要

Fluorine gas discharge laser electrodes and electrode systems that may comprise a plurality of current return tangs extending for less than the respective length of the second elongated gas discharge electrode. In addition electrodes may comprise a first discharge shaping magnet mounted in a first elongated gas discharge electrode and a second discharge shaping magnet mounted in a second elongated gas discharge electrode. Also is an electrode may comprise a crown straddling the centerline axis between the pair of side walls and the pair of end walls, comprising a first material, forming at least a portion of the discharge region of the electrode and a pair of elongated high erosion regions on either side of the crown comprising a second material with a relatively higher erosion rate during gas discharge than that of the first material.
