Abstract

A highly elongated double-clad ribbon fiber that comprises a pure-silica inner cladding with transverse dimensions of 1.4mm by 0.23mm with a linear array of ten ytterbium-doped cores has been fabricated and operated in a simple laser configuration pumped by two diode stacks. The fiber laser yielded 320W of output power at a center wavelength of 1045nm in a combined beam with beam propagation factors of 2 (perpendicular to the array) and 150 (parallel to the array) for 576W of launched pump power. The slope efficiency with respect to absorbed pump power was 62%. The prospects for further power scaling and improved beam quality and efficiency are discussed.
