Experimental Investigation of Power-Scaled Dissipative Soliton Generation

We conduct a power scaling study for the femtosecond dissipative soliton generation with a 10-mu m core diameter, fiber-based, compact-sized, and low-cost all-normal-dispersion laser configuration. Laser performance, in terms of spectra distribution, temporal characteristic, average power, and stability in 8 h, for different filtering bandwidths has been, respectively, investigated. In the experiment, the obtainable highest output power and shortest pulse duration are 4.5 W and 85 fs, respectively. To our best knowledge, this is the shortest pulse duration among the reported all-fiber pumped Watt-level mode-locked fiber lasers.
