摘要： A laser machining device includes a laser oscillator for oscillating a laser beam to have a variable output according to a machining condition, an optical fiber for propagating the laser beam, a sensor for detecting an intensity of a light leaking from a cladding side face of the optical fiber and outputting a detection signal indicating that intensity, and an oscillation control unit for controlling an operation of that laser machining device based on the detection signal. The oscillation control unit compares a first threshold that is set in correspondence to that output with an intensity or an amount of light obtained from the detection signal, compares a second threshold that is set in correspondence to that output with an intensity or an amount of light obtained from the detection signal, and controls the operation of that laser machining device based on a result of comparing.
