Abstract
A discharge-excited laser apparatus includes a pair of discharge electrodes extending in a direction of an optical axis; a plurality of charging capacitors charged by a power source; a plurality of peaking capacitors arranged in parallel in a longitudinal direction of the discharge electrodes and receiving energy accumulated in the charging capacitors; and a plurality of semiconductor switches arranged with conductive plates in the longitudinal direction of the discharge electrodes and connected in series and in parallel to the peaking capacitors. The construction of the semiconductor switches enables uniform shift of the energy in the charging capacitors to the peaking capacitors and reduction of inductance of a loop for capacity shifting.
