Patent ID: 7706424

Claim:
A gas discharge laser system comprising: an electrode power supply system operating at 4 kHz and above including: a magnetic switch pulse compression system having at least one stage of pulse compression between a charging capacitor and a peaking capacitor, the peaking capacitor electrically connected across a pair of electrodes forming a gas discharge region between the electrodes; a high voltage power supply supplying voltage to the charging capacitor; a resonant charger circuit within the high voltage power supply; a connector cable making electrical connection between at least one of: the high voltage power supply and a commutator module; or between the resonant charger circuit and the commutator module; or between the commutator module and the compression head module; or between portions of the high voltage power supply; and wherein the connector cable includes a coaxial cable having a core including a plurality of strands in a litz wire configuration, the litz wire configuration having each one of the plurality of strands insulated from each other one of the plurality of strands and each one of the plurality of strands is wound in a uniform pattern, the uniform pattern minimizing a skin effect for each of the plurality of strands, wherein the skin effect is determined by the operating frequency.
