Abstract

See full text

A fiber coupler is provided, which includes a tubular enveloping structure and several optical fibers arranged in the enveloping structure, each of which has a fiber core and a fiber cladding surrounding same, in order to conduct laser radiation, and each of which extends from the first as far as the second end of the enveloping structure. The enveloping structure includes a tapering section which is tapered in a first direction from the first as far as the second end. In the tapering section, both a first ratio of the diameter of the fiber core to the diameter of the fiber cladding and also a second ratio of the diameter of the mode field of the laser radiation conducted in the optical fiber to the diameter of the fiber core, increases in the first direction for each optical fiber.
