Abstract

A wavelength beam combining device includes: a plurality of laser light sources configured to emit a plurality of laser beams in a first direction and having mutually different peak wavelengths and central axes arranged in a second direction intersecting the first direction; a first diffraction grating disposed at a position where the plurality of laser beams are received, the first diffraction grating being configured to diffract the plurality of laser beams in different directions according to wavelengths of the laser beams to cause the diffracted laser beams to enter the second diffraction grating; a second diffraction grating configured to diffract the plurality of laser beams diffracted by the first diffraction grating to form a wavelength-combined beam, and to direct the wavelength-combined beam in the first direction; and an optical coupling unit configured to couple the wavelength-combined beam to an optical transmission fiber and to be movable in the second direction.
