Abstract
A combined laser source includes: a plurality of semiconductor lasers which contain emission elements emitting a plurality of laser beams and being separately and hermetically sealed; a plurality of collimator lenses which collimate the plurality of laser beams emitted from the emission elements of the plurality of semiconductor lasers; an optical condensing system which receives, condenses, and optically combines the plurality of laser beams collimated by the plurality of collimator lenses; and one or more deflection members which are arranged between the optical condensing system and one or more of the plurality of collimator lenses, and deflect one or more of the plurality of laser beams collimated by the one or more of the plurality of collimator lenses so that the one or more of the plurality of laser beams propagate parallel to an optical axis of the optical condensing system.
