Abstract

PURPOSE:To prevent deterioration and breakdown in the device due to excess discharge current by providing current detectors between each gas discharge path and the DC voltage supply source in a gas laser device in which a plurality of gas discharge paths are constructed by connecting in parallel a plurality of anodes and cathodes. CONSTITUTION:A laser tube 1 consists of anodes 2a and 2b and cathodes 3a and 3b, which are provided inside, and concave reflector mirror 7 and plane output mirror 8, which are provided on both ends, and laser output beam 9 is discharged from output mirror 8. In this structure, anodes 2a and 2b are connected with a DC high voltage source 5. Discharge currents Ia and Ib are supplied to cathodes 3a and 3b respectively via stable resistances 6a and 6b. In addition to these, the circuit is provided with transistors 11a and 11b, reference voltage generators 13a and 13b, a DC power supply 14 and a relay 15. In this structure, when discharge currents Ia and Ib exceed a rated value, the transistor and the relay are operated, the currents between electrodes are shut off, and gaseous discharges in discharge paths 4a and 4b are stopped.
