Abstract
Side-pumping of double clad photonic crystal fibers is experimentally demonstrated. Optical access to the multimode cladding is obtained by collapsing the airholes over a short length of fiber while leaving the inner single mode core undisturbed. Coupling efficiencies above 90% are obtained. A side-pumped Yb fiber laser with a slope efficiency of 81% is demonstrated using this method.
