Abstract
A silent discharge-type laser device in which silent discharge is established to produce a laser output by applying a high-frequency voltage across a set of opposing electrodes, at least one of the electrodes being a dielectric electrode; signals which are fed to the power source which produces a high-frequency voltage, used to modify the amplitude of the high-frequency output or to modify the frequency of the high-frequency output. According, the output voltage produced by the high-frequency power source can be increased or decreased at high speeds.
