Beschreibung
Zusammenfassung:	A laser oscillator which can be protected appropriately from reflected light is provided. A laser oscillator includes a plurality of light detection sensors that detect intensities of different wavelengths of leaking light leaking from an optical fiber that emits a laser beam via filters having different properties, and a control unit that stops oscillation of the laser beam when the intensity of the leaking light detected by any one of the plurality of light detection sensors exceeds a threshold set to each of the light detection sensors.
