Abstract

We present an indirect measurement, using stimulated Raman scattering (SRS), of the fundamental mode effective area in several bent large-core step-index passive fibres used for industrial high-power high-brightness beam delivery. The increase of the SRS gain in bent fibres can lessen the benefit of such large-core fibres.
