摘要

We have fabricated and tested a composite fiber with an Yb3+-doped phosphate glass core and silica cladding. Oscillation with a slope efficiency of 74 was achieved using core pumping at 976 nm with fiber lengths of 48-90 mm in a simple laser configuration, where the cavity was formed by a high-reflectivity Bragg grating and the cleaved fiber end. The measured M-2 factors were as low as 1.05-1.22 even though the fiber was multimode at the lasing wavelength. (C) 2015 Optical Society of America
