FIBER HOLDER AND FIBER LASER APPARATUS
First Claim
1. A fiber holder for holding an optical fiber used in a fiber laser apparatus, the fiber holder comprising:
- a fiber accommodation portion configured to accommodate the optical fiber, the fiber accommodation portion being defined by a main surface on which a helical groove is provided;
an axial member fixed to the main surface so as to pass through a center axis of the helical groove; and
a cover which covers at least a portion of the main surface that is within an outermost circumference of the helical groove,the cover having a central aperture into which the axial member is inserted so as to allow the cover to rotate about the axial member, andthe cover having a cutout that intersects the helical groove from the outermost circumference of the helical groove and extends to an innermost circumference of the helical groove.

Abstract
A fiber holder which can wind an optical fiber easily and accurately, and hold an optical fiber in a wound state is provided. The optical fiber is accommodated in the groove (introduction portion) formed on the fiber bobbin, after that, the bobbin cover is rotated in the rotational direction of the helical groove while the optical fiber is kept in contact with the cutout formed in the bobbin cover. With this, the optical fiber can be accommodated in the groove. Thus, the optical fiber can be wound easily and accurately, and the optical fiber can be held on the fiber bobbin.
