Numerical simulations on dissipative-soliton-resonance generation in an all-normal-dispersion fiber ring laser are presented. Situations with monotonic and periodical saturable absorption are both considered. The multipulse operation in dissipative soliton laser is found to be caused by the spectral filtering effect that limits the spectral maximum width, and the multipulsing can be fully circumvent by inducing strong peak-power-clamping effect of a sinusoidal saturable absorber in the cavity. When the cavity peak-power-clamping effect is strong enough that the pulse peak power and the pulse spectral width are both confined at a low value, the spectral filtering effect induced multipulse operation is prevented and the dissipative-soliton-resonance is generated. Otherwise, the spectral filtering effect causes pulse breaking before the pulse peak power reaches the saturation point. Further results show that under the dissipative-soliton-resonance, the generated pulse peak power can be directly controlled by the cavity peak-power-clamping effect, which is determined by the saturation power of the saturable absorber.
