Abstract: We have developed a cladding pumped tapered erbiumdoped fibre with a record-high core diameter for erbium-doped fibres (100 $\mu$m) and a near diffraction-limited beam quality ($M^2\sim$ 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.

Keywords: tapered fibre, erbium-doped fibre, large mode field.
