The launching efficiencies of the HE1m modes and the overall launching efficiency are calculated when a self-focusing optical fibre is irradiated axially by a Gaussian beam. If the spot size of a Gaussian beam is matched to the characteristic spot size of the fibre, the overall launching efficiency is nearly 100%.
