1. A method for introducing micro-modifications into optical waveguides, the method comprising:
affixing an optical waveguide in a holder of a device such that the optical waveguide and/or the holder is mounted in a movable manner, wherein the device further comprises:
a focusing optical unit for focusing a laser beam pulse into a core region of the optical waveguide;
at least one motor-driven adjustment device for carrying out a linear movement between the optical waveguide and a focus position of the laser beam pulse; and
a rotation device for rotating the focusing optical unit around the optical waveguide;
focusing, via the focusing optical unit, the laser beam pulse onto the focal position, wherein the focal position is positionable in the core region of the optical waveguide, the laser beam pulse is generated by a radiation source within a scope of pulsed operation, and the focusing optical unit is mounted in a movable manner; and
modifying, via the rotation device, a rotational speed of the focusing optical unit while the at least one motor-driven adjustment device moves the focal position through the optical waveguide.
