"Mode-strip connectors are designed for high-power lasers and were developed by us in house; they are currently part of production!"
Light transmission in optical fibers is physically based on the principle of total reflection. Theoretically speaking, the light is reflected multiple times without loss at the interface between the fiber core and fiber cladding. Practically speaking, the fiber cable is imperfect, and small amounts of power can enter the fiber cladding (cladding modes). This presents a challenge in the transmission of high optical power: Just 2–3% is sufficient to destroy the fiber cable.
The mode-strip connector developed by us in house contains a mode stripper, which literally strips the optical fiber of its cladding modes and conducts the generated heat away from the fiber via a cooling element. Our mode-strip assemblies prevent the thermal destruction of the fiber connector.
Mode-strip Assemblies for Many Applications
Optical fiber patch cords with mode-strip connectors are used in particular in the area of high power transmission (e.g., in laser material processing or in the optical pumping of fiber lasers via laser diodes).
Customers also inquire with us when they require high optical beam quality without cladding modes or when thermal hotspots must be avoided in the fiber cladding.
