ABSTRACT:
A method for machining an optical fiber comprises the steps of: connecting a rear end1bof an optical fiber1to a laser oscillator2and exposing a clad12of a front-end1athereof; preparing processing agents4-6containing metal powder that can absorb a laser beam emitted from the laser oscillator2; and soaking the front-end1aof the optical fiber1into or bringing it into contact with the processing agent and, in this condition, emitting the laser beam from the laser oscillator2to irradiate the processing agent with it.
