A position and an orientation of the recesses (29) can be selected to make a delivery of sheath light along the cladding light stripper (20) uniformly, with a uniform temperature distribution is made possible due to the emitted light coat. The recesses (29) on the optical fiber (21) can be formed with the aid of a Laserablationssystems.
