Abstract
An all-fiber tunable, narrowband superfluorescent source is presented by using tunable seed source and two amplification stages. The output power reaches over 30â¯W with the tuning range of â¼35â¯nm (from â¼1045 to â¼1080â¯nm) and the slope efficiency in the final amplifier is about 67%. At the maximum output power, the full width at half maximum is about 0.7â¯nm and the signal-noise ratio reaches over 25â¯dB. More output power can be realized by simply adding pump source. To the best of our knowledge, it is the first time to use all-fiber configuration to realize the tunable output at 1â¯Î¼m superfluorescent fiber source region.
