Abstract
A laser apparatus includes an oscillation stage laser configured to generate and output a pulse laser beam, and an amplification stage laser configured to amplify the pulse laser beam output from the oscillation stage laser. The amplification stage laser includes an optical resonator configured to be a transfer optical system, a first discharge electrode pair and a second discharge electrode pair separated from each other in a first direction intersecting an optical path of the optical resonator, the first and second discharge electrode pairs being disposed across the optical path and configured to alternately discharge, and a slit disposed at a transfer position of the transfer optical system and configured to limit a beam size in a second direction orthogonal to the first direction of the pulse laser beam amplified by discharge of one of the first and second discharge electrode pairs.
