FIBER CUTTING MECHANISM AND LASER LIGHT SOURCE APPLICATION APPARATUS COMPRISING THE MECHANISM

摘要

Provided is a fiber cutting mechanism that prevents secondary utilization of a fiber laser light source incorporated in a device that uses a laser light. With a characteristic fiber cutting mechanism, when a laser device is separated from a laser light source application apparatus, at least a fiber 26 is cut in an specific area from a point within a fiber grating 29 to a connection point between the fiber grating 29 and the fiber 26 containing a laser activating substance (cutting position area (1)).
