In a pulse laser exciting circuit according to this invention, a diode (11) is provided in parallel with a capacitor (4) for generating pulses so as to conduct in the inverse polarity direction of an applied voltage and it prevents that the voltage of inverse polarity generated across the capacitor (4) is applied to the capacitor (4) by conducting the voltage of inverse polarity. The energy due to the voltage of inverse polarity is consumed through the diode (11). Therefore, since neither arc nor streamer is generated between the main discharge electrodes, there is an effect that a pulse laser whose life times of the electrodes are long and which can oscillate at a high repetition rate is obtained. |
