Abstract
A laser oscillator device applies a high-frequency voltage to a plurality of discharge regions through a dielectric for producing a high-frequency discharge for laser pumping. The laser oscillator device has current detectors (CT2a, CT2b) for detecting currents flowing from high-frequency power supplies (26a, 26b) into discharge tubes (1). The current detectors are disposed in positions to detect mutual currents between the adjacent discharge tubes. The currents detected by the current detectors (CT2a, CT2b) are used as feedback currents for preventing uncontrollable conditions of the currents due to a coupling current. The laser oscillator device also has a mechanism for preventing interference in the discharge regions.
