<p>A method and associated apparatus for initiating and guiding an electrical discharge arc. This method preferably comprises the steps of: providing a laser beam through a predetermined gas comprising molecules amenable to vibrational excitation by a laser beam so as to cause vibrational excitation of the molecules and to define a beam path in a direction of desired electrical discharge; and propagating an electrical discharge arc so as to intersect the beam path, whereby the electrical discharge arc is directed along the beam path.</p> |
