    High Power Silica Fiber Cables

    • Special laser fiber structures
    • Cool high power connectors HP-SMA and D80
    • Flexible and robust for high power & bright laser beams

    Laser cables from FlexiRay® product line are the best for laser power delivery with high brightness and beam quality, while High Power connectors of special design stay cool even when mode-stripping effect is provided.

    Robust design of FlexiRay® laser cables secures the long term industrial & medical applications. Bundles of unique metal coated fibers combine power from many lasers - to reach output in multi kW range in any shape.

    Comparison of FlexiRay® cables with a common laser cable

    IR-image of FlexiRay® Fiber Cable with special silica fiber structure & HP connector design -without mode stripper & radiator

    ● Fiber core - 200μm; NA=0.22

    ● Connector – HP-SMA (High Power SMA)

    ● High transmission of fiber cable with 1.5m length provides 53W output of Diode Laser ( λ = 1470 nm)

    ● Temperature of connectors measured with thermopile after 15min of power transmission:for input end – 43°C, for output end – 36.6°C

    ● Insert: visualized profile of output beam for 53W


    IR-image of common Fiber Cable assembled with
    mode stripper & radiator at the output end

    ● Fiber core - 200μm; NA=0.22

    ● Connector – HP-SMA with Mode stripper and radiator

    ● Mode stripper absorbs cladding modes, but cuts off transmission of 1.5m cable to 33W output for Diode Laser at 1.47μm – providing the same beam profile

    ● Temperature of connectors measured with thermopile after 3min for 33W of power output: input end – 44°C, output end – 78°C

    ● Insert: visualized profile of output beam for 33W
