Abstract
A method for producing light includes introducing an ionizable medium for generating a plasma into a chamber. The method also includes applying at least one pulse of energy to a magnetic core that surrounds a portion of a plasma discharge region within the chamber such that the magnetic core delivers power to the plasma which forms a secondary of a transformer according to Faraday's law of induction. The plasma has a localized high intensity zone.
