High-power Yb-doped multi-core ribbon fibre laser
Recent advances in high power cladding-pumped fibre lasers have been dramatic with output powers of up to 1kW reported for a large-core Yb-doped fibre laser [1]. One of the main challenges for efficient power-scaling of fibre lasers is reducing the complexity and increasing the efficiency of the diode pump coupling scheme, whilst preserving the pump beam brightness.
Also, as power levels increase it will necessary to increase the core area to avoid unwanted nonlinear processes and intensity-induced damage. Moreover, a fibre geometry which allows effective removal of waste heat to minimise the risk of thermally-induced damage will also be required. In conventional circular or D-shaped double-clad fibre designs it is necessary to re-shape the diode beam with roughly equal beam quality factors in orthogonal planes for efficient coupling into the fibre. This increases the complexity and the cost of the pump launching scheme and generally results in some reduction in pump power and brightness.

Abstract
Recent advances in high power cladding-pumped fibre lasers have been dramatic with output powers of up to 1kW reported for a large-core Yb-doped fibre laser [1]. One of the main challenges for efficient power-scaling of fibre lasers is reducing the complexity and increasing the efficiency of the diode pump coupling scheme, whilst preserving the pump beam brightness.
Also, as power levels increase it will necessary to increase the core area to avoid unwanted nonlinear processes and intensity-induced damage. Moreover, a fibre geometry which allows effective removal of waste heat to minimise the risk of thermally-induced damage will also be required. In conventional circular or D-shaped double-clad fibre designs it is necessary to re-shape the diode beam with roughly equal beam quality factors in orthogonal planes for efficient coupling into the fibre. This increases the complexity and the cost of the pump launching scheme and generally results in some reduction in pump power and brightness.
