Abstract

In this work we present cost effective all-fiber high power pump laser near 1530 nm. The laser was based on the novel Er-doped fiber with core/cladding diameter of 100/125 μm and optimized core composition. Exploiting of this fiber together with original laser scheme allowed us to reach wall-plug efficiency as high as ~17.5 % and, at the same time, provide robust wavelength-stabilized operation. Developed laser was tested as a pump source for single-mode Tefloncoated double-clad Er-doped fiber at 1585 nm. Slope efficiency of 45 % was demonstrated in MOPA configuration
