Abstract:
A laser apparatus includes: a laser chamber in which a pair of discharge electrodes is provided; a first beam expander configured to expand a beam width of a beam outputted from the laser chamber at least in a first direction substantially parallel to a direction of electric discharge between the discharge electrodes; and a line narrow optical system including: a second beam expander configured to expand a beam width of the beam outputted from the laser chamber at least in a second direction substantially perpendicular to the first direction, the second beam expander including at least one optical element and a grating configured to perform wavelength dispersion of the beam expanded by the first and second beam expanders, the wavelength dispersion being performed in a plane substantially parallel to the second direction, wherein at least one of the grating and the at least one optical element is arranged so as to compensate for wavelength dispersion caused by the first beam expander.

Claim (Index 9):
The laser apparatus according to  claim 6 , further comprising:\n a rotation mechanism configured to rotate one prism of the third prisms and a prism of the at least one optical element provided nearer to the laser chamber than the third prism, the one prism being rotated around an axis parallel to the first direction.
