| Zusammenfassung: | A laser apparatus includes: an oscillator configured to output seed light; an amplifier including a laser chamber provided in an optical path of the seed light and a pair of discharge electrodes provided inside the laser chamber; and a transform optical system provided in the optical path of the seed light between the oscillator and the amplifier and configured to transform the seed light in a way that suppresses a decrease in purity of polarization of a laser beam that is outputted from the amplifier. |
