WIPO Patent Application WO/2023/007831
Kind Code:
A1
Abstract:
This fiber laser device comprises: an enclosure; a first optical element that is for oscillating laser light and that has a first fiber and a first fiber connector provided at an end of the first fiber; a second optical element that is for oscillating laser light and that has a second fiber and a second fiber connector provided at an end of the second fiber; and a movable holder that holds the second fiber connector and that is movable so that the orientation of the second fiber connector changes between a first orientation and a second orientation. The first optical element and the second optical element can be optically connected via the first fiber connector and the second fiber connector. A first opening is formed in a wall section of the enclosure. The first orientation is an orientation in which the first optical element and the second optical element are optically connected, and the second orientation is an orientation in which an end face of the second fiber is exposed via the first opening.
