Abstract

A light amplification device comprising an outer electrode (30) defining an annular passage therethrough (40) and an inner annular electrode (20) located within the annular passage (40), the inner and outer concentric annular electrodes defining a gas discharge region therebetween, the inner electrode being electrically isolated from the outer electrode, wherein the outer electrode is grounded and the inner electrode is operable to receive current therethrough, such that when current is passed through the inner electrode, electrical discharge occurs in the gas discharge region.
