Recent progress in the design of passive and active fibres for use in high power fibre lasers and amplifiers at visible and near-IR wavelengths
By employing nonlinear frequency conversion on the polarized and spectrally narrow outputs of such fibre lasers it is possible to generate lasing output in the visible and ultraviolet. In this paper we review the recent progress in fibre design that is facilitating the scalability of the output power of fibre-based lasers and amplifiers.
