19 May 2010 Multicore fibers for high-brilliance laser beam delivery
Author Affiliations +
A passive few-mode multicore fiber consisting of 7 coupled cores is investigated. The fiber is compared to a largemode- area step-index fiber, with the same number of modes and a similar mode field area. Based on the 7-core fiber results a single transverse mode multicore fiber, with a mode field area of 465 μm2 at 1050 nm, delivering virtually diffraction limited output beam quality is demonstrated. Stimulated Raman threshold measurements are presented and a fundamental mode high-power beam transport with more than 350 W is shown.
