New microstructured optical fibers for innovative lasers (Conference Presentation)

Paper Abstract

The 4F consortium has obtained new results on microstructured optical fibers for the development of Ytterbium active fibers with a large core but also of hollow fibers for the transport of the laser beam. The active fiber core composition aims to ensure good performance in aging and photodarkening. The fiber specifications are a Mode Field Diameter greater than 30 μm, a Polarization Extinction Ratio more than 15 dB, a cladding absorption at 976 nm more than 10 dB/m, bending over a relatively small diameter (about 20cm). The fiber will allow a laser operation exceeding 150 W.
