  • Brightness preserving fiber beam combiner for reduced nonlinearities and intense radiation damage durability
    Patent number: 10359587
    Abstract: Method for adapting a fiber beam combiner to transmit at least 20 kW of optical power without noticeable bulk material damage mechanism effect and destructive nonlinearities, the method comprising: connecting an adiabatic beam combiner with a splice connection to an input facet of a graded index fiber which has a core doped with an index increasing material, further comprising the step(s) of: restricting the numerical aperture of the graded index fiber, and/or selecting the index increasing material with a Raman gain lower than that of GeO2 such as Al2O3 or Y2O3, and/or placing a shroud tube around the graded index fiber core, said shroud tube comprising a fluorine-doped silica tube.
    Type: Grant
    Filed: March 11, 2015
    Date of Patent: July 23, 2019
    Assignee: Soreq Nuclear Research Center

  • All-fiber low mode beam combiner for high power and high beam quality
    Patent number: 9268095
    Abstract: A low mode beam combiner (10) including individual entry fibers (12) that maintain a low mode operation, an exit fiber (16), and a spliced section (14) including a bundle of spliced entry fibers (12), in which a bundle diameter is reduced to a LMA (large mode area) core of the exit fiber (16).
