ABSTRACT:
In an arc discharge device, a thin film bridges the gap(s) between adjacent electrodes, thereby enabling the arc discharge to be initiated and sustained by a low voltage D.C. supply. Application of the invention to both light source (e.g., laser) and material working (e.g., metal deposition) embodiments is described. One of the light source embodiments utilizes a cathode electrode which includes a pool of liquid Hg to generate a Hg ion plasma.
