PURPOSE:To reduce the restriking voltage between main electrodes after main discharge has vanished, and obtain stable laser output, by connecting a saturable reactor in parallel with a discharging part constituted of a pair of main electrodes and peaking capacitors for preliminary ionization which are connected in parallel with said main electrodes. CONSTITUTION:A saturable reactor 20 is connected in parallel with a discharge part 11 wherein a pair of main electrodes 5, 5 and peaking capacitors 4, 4 for preliminary ionization are connected in parallel. By suitably selecting the iron core sectional area, the iron core material, and the number of turns of winding of the saturable reactor 20, the saturation point of the reactor 20 is set to be a little higher than the voltage to maintain the main discharge. Hence the saturable reactor 20 immediately operates after main discharge has vanished and then a voltage is again generated. In the pulse laser oscillating equipment constituted in this manner, when a voltage is again generated after the main discharge has vanished, the saturable reactor immediately operates and decreases the voltage applied to the discharging part, so that stable laser output can be obtained. |
