Abstract
A charging and discharging circuit for a pulse laser which enables the pulse laser to increase an oscillation frequency. A charging and discharging circuit for a pulse laser, comprising a high-voltage power supply (18) for charging a capacitor (C0) with electric charges until an interpolar voltage reaches a final target value VF, a discharging circuit (3) for discharging the electric charges in pulses between discharge electrodes (5, 5) to oscillate a pulse laser beam (11), and a laser controller (4) for calculating a final target value VF of an interpolar voltage VC for the next charging on the basis of the pulse light emission amount per pulse of the pulse laser beam and outputting the value to the high-voltage power supply, wherein the high-voltage power supply starts charging the capacitor with electric charges toward the predetermined primary target value V1 before the laser controller calculates the final target value VF of the interpolar voltage VC and wherein the charging is performed up to the final target value after the calculation thereof.
