A laser apparatus () has a plurality of light sources (to) that include laser array stacks (to). Laser beams () are respectively deflected by a slit mirror () and a polarizing beam splitter () and synthesized with other laser beams (). These laser beams have optical axes that are inclined with respect to each other and slow axis directions that are mutually parallel. A converging optical system () converges the laser beams from the respective light sources at positions that are separated along a direction perpendicular to the slow axis directions.
