We present a new passive air/silica microstructured optical fiber designed to be single mode and which delivers a flat-top intensity profile at 1 μm. By inclusion of a raised index ring surrounding the central core, the refractive index profile of the fiber flattens the intensity distribution of the fundamental mode. Experimental results clearly demonstrate the feasibility of all-fibered top-hat beam delivery systems with one spatial mode suitable for many applications.
