Title:
ビーム重ね機構を備えた光ファイババンドル
Document Type and Number:
Japanese Patent JP7252198
Kind Code:
B2
Abstract:
Provided is a condensing apparatus that can form an irradiation spot of the laser beam having a large power density by combining a plurality of laser lights without using a power combiner. An optical fiber bundle is formed of a bundle of a plurality of optical fibers, one end thereof forms an incident side bundle end at which light incident ends of individual optical fibers are arranged, and the other end forms an emission side bundle end at which light emission ends of individual optical fibers are arranged. The optical fiber bundle includes, at the emission side bundle end, an optical deflection unit that deflects at least two light beams toward different directions, respectively, such that the at least two light beams emitted from respective light emission ends of at least two optical fibers out of the plurality of optical fibers overlap each other on at least one cross section that is at rear on an optical path of the emission side bundle end and are then scattered.
