Efficient cladding pumping of an Er³⁺ fibre

Abstract

We report for the first time efficient operation of a cladding pumped Er³⁺ fibre configured in both fibre laser and fibre amplifier form. The fibre was of a double clad design compatible with beamshaped 980nm broadstripe pump lasers An efficiency in excess of 40% has been achieved.
