Highly ytterbium (Yb3++)-doped double-clad phosphate fiber was fabricated for the investigation of power scaling of a 976 nm single-frequency laser. Over 3+ W single-frequency laser output power was obtained with gain fibers shorter than 10 cm. Our experimental results show that Yb3++-doped phosphate fiber is a promising gain medium for 976 nm laser amplifiers.
