Abstract

Abstract: We have developed a cladding pumped tapered erbium-doped fibre with a record-high core diameter for erbium-doped fibres (100 mm) and a near diffraction-limited beam quality ( μ 2 ∼ 1.3). Optimisation of the tapered fibre parameters provided a high (18 %) efficiency of pump radiation conversion at a wavelength of 976 nm into signal radiation at a wavelength of 1560 nm.
