Abstract
A semiconductor laser device includes: semiconductor laser arrays; collimating members; a condenser lens provided, in common, for collimated light beam arrays outputted from the respective collimating members, and including a light incident surface on which a light incident row pattern including light incident regions is formed through entering of the collimated light beam arrays; and an optical fiber. A condenser lens incident optical path length of at least one of the semiconductor laser arrays is different from that of any other one of the semiconductor laser arrays. A collimated light beam array derived from one of the semiconductor laser arrays that corresponds to the largest condenser lens incident optical path length is directed to a predetermined light incident region in the light incident surface. The predetermined light incident region is other than the outermost light incident region in the light incident row pattern.
