Abstract
The multi wavelength laser device includes a laser light sourcethat emits a plurality of laser lightswhose fundamental wavelengths differ from one another, a dispersing elementthat changes the traveling direction of each of the plurality of laser lights according to the wavelength and the incidence direction, and that emits the laser lights in a state in which the laser lights are superposed on the same axis, and a wavelength conversion elementthat has a plurality of polarization layers disposed therein and having different periods, and that performs wavelength conversion on the fundamental wave laser lights emitted from the dispersing elementand placed in the state in which the laser lights are superposed on the same axis, and emits a plurality of laser lightsacquired through the wavelength conversion in a state in which the laser lights are superposed on the same axis.
