We present results of an experimental investigation of the optical losses produced by bending large core optical fibres, typical of those used in power beam delivery systems. Experiments have been conducted over a range of core diameters for both plastic clad silica and all silica fibres, as a function of bend radius. A theoretical model has been developed for predicting the magnitude of the bend loss, and agreement was obtained with the experimental results. The study thus yields design information for fibre beam delivery systems.
