PURPOSE:To provide a laser device with rigidity and long life by a method wherein, in a nitrogen laser device utilizing a broom line circuit comprising main discharge electrodes, accumulators, discharge tube, high impedance elements, a ceramic insulating plate is utilized for a broom line substrate and metallic films are evaporated down to both sides of the substrate to produce accumulators. CONSTITUTION:Main discharge electrodes 11 and 12 confronting to each other are provided in an outer case 7 and a high impedance element 5 is connected to the ends of these electrodes 11 and 12 in parallel while one end of them is likewise connected to a DC high voltage power supply 8 outside the outer case 7 through the intermediary of another high impedance element 6. On the other hand, the outer surfaces of the electrodes 11 and 12 are connected to both grounded capacitors 2 and 3 while the capacitor 2 is further connected to a starting trigger electrode 9 outside the outer case 7 through the intermediary of a starting discharge tube 4. In such a constitution, a ceramic insulating plate may be utilized for a substrate 10 comprising the electrodes 11 and 12 and the capacitor 2 and 3 while a grounding electrode 11 for capacitors is provided on the backside and discharge starting electrodes 12 are formed under the electrodes 11 and 12. |
