Abstract
A semiconductor laser apparatus, including: a beam divergence angle correction optical system for correcting a divergence angle of beams generated from light emitting points of a semiconductor laser bar; a beam rotation optical system for rotating the beams each having the corrected divergence angle; a wavelength dispersion optical element having a wavelength dispersion function; and a partial reflection mirror. A relative position of the beam divergence angle correction optical system with respect to the light emitting point in a divergence angle correction direction is changed for each light emitting point.
