ABSTRACT:
A laser having an electrode assembly which reduces the formation of glow-to-arc transitions. The electrode assembly of the present invention includes a cathode sub-assembly placed in opposition to an anode sub-assembly, with a main discharge region defined between the two. The cathode assembly includes an electrode in electrical contact with a cathode plate, the latter of which is formed from negative temperature coefficient of resistivity (NTC) material. The anode assembly includes an anode to which is mounted at least one structural member, at a position away from the main discharge region. This structural member is separated from the edges of the cathode plate by a gap, across which arcs may form.
