Paper Abstract

A novel design in the inner cladding of a cladding-pumped ytterbium-doped fiber is presented. The fiber includes a modification of the inner cladding by the insertion of four D-shaped holes distributed around the core in a square configuration. This novel fiber structure makes the device efficient in absorbing the pump power while keeping the overall circular structure. As a result, up to 5 W of single mode at 1095 nm from a 7 W of absorbed pump power was achieved; the slope efficiency was 60% wrt. launched pump power and the beam quality was measured to be 1.2 implying that our laser has a diffraction limited output beam.
