<p>An electric discharge apparatus, not being a laser, includes a power supply, a chamber (21) and at least one pair of electrodes (5, 6) defining an electric discharge path in the chamber along which a glow discharge is to be generated. One electrode, which at least at some time is an anode, has a porous surface and gas is injected into the chamber (21) through the porous surface.</p> |
