ABSTRACT:
The semiconductor laser device1A has a semiconductor laser array3including a plurality of active layers2arranged in parallel along a slow direction, and outputs laser beams from the front end face2aside of the active layers2.The semiconductor laser device1A comprises a collimating lens5that collimates laser beams L1outputted from the respective rear end faces2bof the active layers2within a plane orthogonal to the slow axis, and a reflecting mirror9that feeds back parts of the laser beams L2outputted from the collimating lens5to the respective active layers2via the collimating lens5.
