| description | PROBLEM TO BE SOLVED: To provide a fiber laser device, a laser processing apparatus, and a laser processing method, capable of obtaining high power pulse laser beams efficiently. SOLUTION: In the fiber laser device, the laser processing apparatus, and the laser processing method, the fiber laser device includes: a first seed light source for emitting first pulse seed beams; a second seed light source for emitting second pulse seed beams having a wavelength different from that of the first pulse seed beams; an excitation light source for emitting an excitation light; and an optical fiber in which a rare-earth element added to a core absorbs the excitation light, and which emits first laser beams having first amplified beams in which the first pulse seed beams are amplified and second amplified beams in which the second pulse seed beams are amplified.
