ABSTRACT:
A discharge excitation type short pulse laser device is provided with a preliminary ionization circuit, the effeciency of preliminary ionization of which is remarkably improved. The laser device comprises a main discharge circuit including first and second main electrodes which are confronted with each other in a laser medium, main discharge capacitor means for storing energy for main discharge, and a discharge starting high voltage switch; and a preliminary ionization circuit connected to said high voltage switch, said preliminary ionization circuit including a discharging gap for preliminary ionization, a preliminary ionization capacitor and an inductance.
