Abstract
A fiber laser apparatus that generates invisible laser light using an amplification optical fiber having a single-mode core and outputs the invisible laser light via an output optical fiber is provided. The fiber laser apparatus includes a visible laser light source that generates visible laser light, an introducing section that introduces the visible laser light generated by the visible laser light source into a core of one of the amplification optical fiber and the output optical fiber, and a drive unit that drives, in a case of performing alignment of an irradiation position of the invisible laser light with respect to a workpiece, the visible laser light source and emits the visible laser light via the core of the output optical fiber.
