Original Abstract Submitted
A laser apparatus includes: a first laser device that forms a first beam group; a second laser device that forms a second beam group; an output mirror that constitutes an end of an external resonator; a converging optical system that allows non-parallel incidence of the first and second beam groups on the converging optical system; a diffraction grating disposed at an intersection at which at least a part of the first and second beam groups is superimposed, and having a diffraction effect in a plane perpendicular to a third direction that is a direction perpendicular to first and second directions; and a collimating optical system disposed between the diffraction grating and the output mirror, and collimating the first and second beam groups such that the first and second beam groups are incident perpendicularly on the output mirror while being spatially separated from each other.
