Increased coupling efficiency in standard 980-nm pum¥lasers is realized from re-engineering the optical coupling between the pump-laser chi¥and fiberoptic pigtail. The increased efficiency results in the 150-mA laser current now producing 84 mW, u¥from 63 mW. Users can realize transmission of higher power over fiber for long-distance transmission, lower drive current at fixed power levels, and increased lifetime.
