Abstract
A fiber coupling device includes a housing and a window provided in the housing. The fiber coupling device is configured to collectively guide plural laser beams to at least a first fiber, the plurality of laser beams each being emitted from a corresponding one of plural external laser light sources and entering through a laser beam inlet. The housing is configured such that the laser beams enter the housing from the laser beam inlet. The window is provided inside the housing and faces the laser beam inlet. The fiber coupling device is not required to detach when an optical axis is adjusted.
