Abstract
A discharge excitation type short pulse laser device which is constructed with first and second main electrodes disposed in confrontation with the direction of the laser beam axis as their longitudinal direction, an auxiliary electrode provided on the rear surface part of the second main electrode and opposed to the second main electrode through the dielectric member, a pulse circuit for applying a pulse voltage across the first and second main electrodes, and a circuit for applying a voltage across the auxiliary electrode and the second main electrode, the circuit forming a part of the pulse circuit, or being independent of the pulse circuit, wherein the second main electrode is made of an electrically conductive material having a plurality of apertures therein, the second main electrode and the dielectric member are disposed in tight adhesion each other, and the second main electrode is thinly formed to enable creeping discharge to be produced on the surface of the dielectric member, thereby distributing electrons to be the seed for the main discharge to be generated across the main electrode.
