We present an all-anomalous mode-locked laser architecture combining a few-mode gain fiber with single-mode passive fibers. This hybrid fiber laser generates high-energy pulses whose features are controlled by an intracavity spectral filter. Using a 1.7-nm filter bandwidth, the laser delivers 2.5-ps pulses of 39-nJ energy and 15.6-kW peak power. Increasing the filter bandwidth to 12 nm, the laser delivers nearly Fourier-transform limited 230-fs soliton pulses with 2.1-nJ pulse energy and 9-kW peak power. These results validate the scalability and flexibility of the energy-managed soliton laser approach for generating high-energy dissipative solitons in the anomalous dispersion regime with adjustable duration.
