An optical fiber is designed to transmit high-power laser radiation. The optical fiber includes a fiber core, and an inner fiber cladding surrounding the fiber core, where the inner fiber cladding is configured to carry the laser radiation in the fiber core. The optical fiber also includes a first outer fiber cladding surrounding the inner fiber cladding. The first outer fiber cladding has a capillary-free longitudinal section and has a smaller refractive index than the refractive index of the inner fiber cladding. The optical fiber includes an outermost fiber cladding surrounding the first outer fiber cladding. The outermost fiber cladding has scattering centers that surround the capillary-free longitudinal section, where the scattering centers scatter laser radiation emerging from the inner fiber cladding through the first outer fiber cladding along the capillary-free section.

A system provides for remote communication between a service computer and a machine control at a machine. The system includes at least one central computer that is protected by a Firewall, a connection between the service computer and the central computer, and communication connections that are allocated to each of the machine controls. The at least one central computer includes a plurality of virtual computers. Each communication connection is associated with a virtual computer. The central computer can be connected to a particular machine control through the virtual computer that is set up for the communication connection allocated to the particular machine control.

The aim of the invention is to obtain a laser system with the highest possible power that operates as stably as possible. This object is achieved in the case of a laser system by the laser radiation field passing through at least two laser-active solid bodies of identical material disposed one following the other in the direction of its beam axis, by the pumping radiation guide being formed in such a way that it feeds into each of the solid bodies the first partial radiation field via one end face and the second partial radiation field via the other end face and by the pumping radiation guide being formed in such a way that a pumping power fed into each of the at least two solid bodies by the two partial radiation fields can be adjusted in such a way that the effects on the laser radiation field of thermal lenses produced by the pumping power in each of the at least two solid bodies are substantially identical.
