Paper Abstract

A new method for side-pumping double-cladding fiber was researched. A quartz column of 3mm length was cut away from D-shape double-cladding fiber which has a transverse sectional dimension of 350μm×400μm. Then the column-fiber coupler was fabricated by gluing the column onto the side of inner cladding . The pumping light was coupled into the inner cladding from the end of the D-shape quartz column. When the output power was 1.3W from the forward end of the coupler, the optimum efficiency is 85%. This method can be suitable for pumping the fiber laser and amplifier of several watts output power.
