PROBLEM TO BE SOLVED: To provide a fiber laser oscillator with a more efficient and simpler structure and with high output and to provide a method of manufacturing the fiber laser oscillator. SOLUTION: An optical fiber for fiber laser 10 is spirally wound. An outgoing face of one exciting light guide fiber 20 is bonded to the optical fiber for fiber laser 10 in n-th winding ((n) is arbitrary integer of one or above) so that respective outgoing faces of a plurality of exciting light guide fibers 20 where exciting light is guided follow a winding direction of the wound optical fibber for fiber laser 10. The exciting light guide fiber 20 is bonded to the optical fiber for fiber laser 10 by a prescribed angle so that guided exciting light is confined in a bonding place. COPYRIGHT: (C)2009,JPO&INPIT |
