<p>A method of producing a field emission cathode for a light source, and including at least one field emitting body having a field emitting surface, wherein the method includes modifying said emitting surface so as to provide at least one electric field emitting irregularity in each said surface. The method is distinguished by at least one beam of laser light being brought to shape the body and to simultaneously contact the field emitting surface and thereby provide a modifying treatment to the surface of the body. The invention also concerns a field emission cathode so produced and a light source including such a field emission cathode.</p> |
