Abstract
A laser device causes, with a plurality of laser media that generate laser beams having wavelengths different from one another, a convergent lens to cause laser beams each emitted from the plurality of laser media to overlap one another on a dispersive element to form a single combined beam. The dispersive element is positioned where the plurality of laser beams are caused to overlap one another by the convergent lens to form a single beam, causes a portion of the plurality of laser beams to return back toward the laser media as a first laser beam flux, and outputs another portion of the plurality of laser beams as a second laser beam flux having a single optical axis.
