Abstract
A multiplexing laser light source which can easily couple a plurality of laser lights to a fiber having a core of such a size as to be difficult to align the laser lights therewith. The multiplexing laser light source includes: a plurality of semiconductor lasers, each of which outputs a laser light; a fiber having a core and a cladding, the fiber including a mode stripper mechanism configured to remove a cladding mode light on an incident side on which the laser light is incident; a coupling lens couples the laser lights emitted from the plurality of semiconductor lasers to the fiber by condensing the laser lights; an output monitor to monitor an output of the fiber; a ferrule attached to the incident side of the fiber and configured to absorb the cladding mode light; and a temperature monitor configured to monitor a temperature of the ferrule.
