High Power Fiber

Fiberguide Industries offers fibers specifically designed for demanding high power applications such as material processing and fiber lasers. Our standard high power fiber offering is detailed below and on the accompanying spec sheets. Please contact us for any non-standard fiber needs: Custom Core / Cladding Sizes, Custom NAs, Narrow / Broad Wavelength Transmission, etc.

Please use the following calculator to calculate fiber sizes or laser power requirements for your system.

The calculator includes the capability to make calculations for pulsed laser systems and continuous wave laser systems. Calculate laser specs and requirements based on fiber size, or calculate the necessary fiber size for a given laser light source.

If you have custom requirements or design questions, please contact us and our experienced engineers will work to create a solution that fits your needs.

UniClad Fiber

Silica Core / Silica Clad / Polymer Coated Fiber

UniClad

Fiberguide’s Universal Clad, or UniClad, optical fibers are Silica Core/Silica Clad/Polymer Coated fibers designed for high power transmission and other applications where a large cladding relative to the core is beneficial. These fibers feature a fixed 500μm cladding diameter, with a 100μm – 400μm core size, making laser alignment and splicing easier. The larger 600μm and 800μm core sizes use proportionally larger cladding.

Cross-Section-Polyimide-Fibers

Silica Core / Silica Clad / Polymer or Metal Coated Fiber

Fiberguide’s SFS and AFS fibers are primarily used in photonics applications where individual or bundled large core (>50µm) multimode fibers are needed for the transmission of optical energy. These fibers can be coated with a variety of polymers or metalized, for extreme temperature performance.
