The generation of mode-locked dissipative soliton pulse from an all-fiber ytterbium-dope laser based on nonlinear polarization rotation without dispersion compensation and additional filter has been demonstrated experimentally and numerically. The formation of the dissipative soliton pulse is a self-consistent result of various effects in the laser including positive fiber dispersion, nonlinearity, cavity transmission, gain saturation, and filtering over one cavity round trip. Stable mode-locked pulses with pulse energy of 1.1 nJ have been achieved. The operation of the dissipative soliton lasers is numerically simulated, which agrees with the experimental results.
