Abstract :
An Yb-doped fibre laser with a helical core trajectory in the cladding material has been demonstrated for the first time. The laser yields 350 mW of linearly-polarised, single-spatial-mode output at 1047 nm from a multimode core of diameter, 26 (mu)m, and numerical aperture, 0.14, when core-pumped by an Yb:YAG laser at 1030 nm.
