<p><P>PROBLEM TO BE SOLVED: To obtain simple and small fiber laser processing equipment excellent in maintenance performance in which a high output fiber laser beam suitable for laser processing can be obtained conveniently. <P>SOLUTION: The fiber laser processing equipment comprises a fiber laser oscillator 10, a laser power supply 12, a laser incident part 14, a fiber transmission system 16, a laser exit 18, and a processing table 20. The fiber laser oscillator 10 includes an optical fiber 22 for oscillation, an electrooptical pump 24 for irradiating one end face of the oscillation fiber 22 with pumping light MB, and a pair of optical resonator mirrors 26 and 28 opposing optically through the oscillation fiber 22. The optical fiber 22 for oscillation includes a core extending on its central axis, a clad surrounding the core, an air layer surrounding the clad, and a holder for holding the air layer while surrounding. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
