Abstract

PURPOSE:To make applied voltage constant and set the length of a discharge tube freely by conducting AC discharge in the diametrical direction of the discharge tube. CONSTITUTION:A pair of electrodes 12, 13 are mounted on an outer surface of a discharge tube 1 consisting of a dielectric in closely adhering shapes. A pair of these electrodes 12, 13 are formed on the outer surface in shapes that are opposed in the diametrical direction of the discharge tube 1. Such electrodes 12, 13 are made up by normally projecting melted aluminum onto the outer surface of the discharge tube 1. A high-frequency power source 14 is connected to one electrode 12 and the other electrode 13. The high-frequency voltage of several tens-several hundred kHz and several kV is applied to a pair of the electrodes 12, 13 from the high-frequency power source 14, AC discharge (silent discharge) repeating generation and extinction every each half cycle of the frequency of the power source is produced, and laser excitation is conducted.
