In this abstract, the performance of optically uncoupled cores in 9-core multi core fibers for high-power fiber lasers is evaluated by considering thermal effects due to the heat load originated by quantum defect between pump and laser radiation. For high power applications, thermal effects are currently seen as the main constraint to power scaling of fiber lasers. The finite-element method is employed to model the optical field distribution for optical amplification and lasing, in order to analyze the effect of heat load on the modes of ytterbium-doped multi-core fibers.

Abstract
In this abstract, the performance of optically uncoupled cores in 9-core multi core fibers for high-power fiber lasers is evaluated by considering thermal effects due to the heat load originated by quantum defect between pump and laser radiation. For high power applications, thermal effects are currently seen as the main constraint to power scaling of fiber lasers. The finite-element method is employed to model the optical field distribution for optical amplification and lasing, in order to analyze the effect of heat load on the modes of ytterbium-doped multi-core fibers.Pubblicazioni consigliate
