Claims

[Scope of utility model registration request]

The energy stored in the charging capacitor is transferred to multiple peaks by an electric switching element through a saturable reactor connected by a connecting medium to the electrode support plate of the main discharge electrode provided in the chamber filled with laser medium gas. - After the laser medium gas is pre-ionized by the gap discharge of the pre-ionization electrodes which are transferred to the capacitors and connected in series to these peaking capacitors and in parallel to the main discharge electrode, the charging voltage of the peaking capacitors is set to a predetermined value. In a discharge-excited pulsed laser device that generates a glow discharge between the main discharge electrodes and oscillates a laser when the saturable reactor reaches a certain value, the saturable reactor is configured to have an elongated shape comparable to the length of the main discharge electrode. A discharge-excited pulsed laser device, characterized in that the center line in the longitudinal direction and the width direction thereof is arranged so as to coincide with the center line in the longitudinal direction and the width direction of the pre-ionization electrode group.
