PURPOSE:To provide a pulse laser oscillating system which substantially alleviates the operating duty of a switch, and is capable of enlarging an operating region of a laser. To improve the oscillation efficiency by making it possible to effect an external control. CONSTITUTION:First capacitors 21 and second capacitors 22 are connected in series to each other between a pair of main electrodes 1 and 2 arranged opposite to each other within a container hermetically filled with a laser gas, and contact points between the capacitors are grounded. The first capacitors 21 are pulse-charged by a first power supply circuit, for example, including a high voltage power source 9, a charge resistor 8, a capacitor 5, and a switch 7. The second capacitors 22 are d.c. charged by a second power supply circuit, for example, including a high voltage power source 23 and the charge resistor 8. There are provided a first control means 28 for controlling the discharge start time of electric discharge 11 and a second control means 28 for controlling a voltage of the second power supply circuit. |
