Abstract:
An optical power monitoring device detects an optical power propagating through an optical fiber including at least a core and a cladding. The optical power monitoring device includes: a first optical fiber; a second optical fiber having a larger core diameter than the first optical fiber; a connection part where an end surface of the first optical fiber and an end surface of the second optical fiber are spliced; a first leakage part for leakage of a beam from the first optical fiber to the outside; a second leakage part for leakage of a beam from the second optical fiber to the outside; a first photodetector that detects an optical power leaking from the first leakage part; and a second photodetector that detects an optical power leaking from the second leakage part.

Claim (Index 12):
The laser apparatus according to  claim 11 , further comprising a recording unit and a calculation unit, wherein\n the recording unit contains a first detection characteristic and a second detection characteristic recorded in advance, the first detection characteristic showing a relationship of a detection value obtained from the first photodetector with an output command value from the control unit in the absence of a reflected beam from a workpiece as a laser machining target, the second detection characteristic showing a relationship of a detection value obtained from the second photodetector with the output command value from the control unit in the absence of a reflected beam from the workpiece, the calculation unit calculates a first reflected beam power during laser machining based on a detection value obtained from the first photodetector relative to the output command value from the control unit and the first detection characteristic, and a second reflected beam power during the laser machining based on a detection value obtained from the second photodetector relative to the output command value from the control unit and the second detection characteristic, at least one threshold is set individually for each of the first reflected beam power and the second reflected beam power calculated by the calculation unit, and if the threshold is exceeded, the control unit instructs interruption of beam output or operates so as to change the output command value by following a predetermined standard.
